Who are white nationalists and what do they want?

A quaint Virginia college town still wrestling with the legacy of slavery became the scene of deadly protests this weekend as white nationalists and other right-wing groups clashed with counterprotesters over the planned removal of a statue of Confederate Gen. Robert E. Lee from a city park.

Men carrying Confederate flags stood side by side with the Ku Klux Klan, neo-Nazis and rifle-toting militia members in Charlottesville at a rally dubbed “Unite the Right.” Chanting “You will not replace us,” they exchanged blows and volleys of pepper spray with protesters opposed to their presence.

As police dispersed the crowds, a car plowed into counterprotesters, killing one person and injuring 19 others. At least 15 people were also injured in skirmishes.

Gov. Terry McAuliffe declared a state of emergency and called in the National Guard. The Southern Poverty Law Center described the event as possibly the “largest hate-gathering of its kind in decades.”

But who are white nationalists and what do they want?

What is white nationalism?

What is the alt-right movement?

02:33 - Source: CNN

The term white nationalism originated as a euphemism for white supremacy, the belief that white people are superior to all other races and should therefore dominate society, according to Oren Segal, director of the Anti-Defamation League Center on Extremism.

People who hold these beliefs sometimes go by other names, including Alt-Right, Identarians and race realists. However, this is simply a rebranding – “a new name for this old hatred,” Segal said.

Richard Spencer, president of the National Policy Institute and the editor of Radix Journal, is credited with coining the term Alt-Right.

“I don’t use the term white nationalist to describe myself,” he said.

“I like the term Alt-Right. It has an openness to it. And immediately understandable. We’re coming from a new perspective.”

Other white supremacist groups include the Ku Klux Klan and neo-Nazis. But most white supremacists aren’t affiliated with an organized group, Segal said. Some also take measures to distance themselves from known hate groups, like the KKK.

“This lack of affiliation makes them harder to track, and also means that any groups that do emerge tend to be extremely flexible and porous,” he added.

Some Klansmen still favor white robes and hoods. But groups like the Alt-Right, overwhelmingly made up of Millennial men, prefer khakis and collared shirts. They’re active on social media and employ irony and humor in their messaging, Segal said.

But the goal is the same: a white ethno-state where each race lives in a separate nation.

White supremacists and their ilk see diversity as a threat, Segal said. A popular white supremacist slogan is, “Diversity is a code word for white genocide.”

George Hawley, a political scientist at the University of Alabama, said a sense of white victimhood is key to the movement.

“There is a sense that whites are under siege and being deliberately dispossessed by hostile elites who wish to usher in a new multicultural order,” Hawley said.

“They dislike the culturally-foreign immigrants who enter the United States and work for low wages, and they dislike the political and economic elites that invite them in. They are also hostile to the media and academia, which they contend push an anti-white message.”

Torch-bearing white nationalists march on UVA

You’re getting a glimpse of it right now, according to Daryl Johnson, owner of domestic terror monitoring group DT Analytics and a former counterterrorism expert at the Department of Homeland Security.

“The anti-immigration xenophobia is rising,” Johnson said. “US policy is becoming more isolationist – the building of the (border) wall, the travel ban, mass deportations. These were ideas that I read about 10, 15 years ago on white supremacist message boards. Now they’re being put forth as policy.”

Hundreds of white nationalists, neo-Nazis and members of the "alt-right" march down East Market Street toward Lee Park during the "United the Right" rally August 12, in Charlottesville, Virginia. After clashes with anti-facist protesters and police the rally was declared an unlawful gathering and people were forced out of Lee Park, where a statue of Confederate General Robert E. Lee is slated to be removed.

Johnson recounted a chilling chapter from “The Turner Diaries,” a fictional account of a white supremacist guerrilla army that has been called the “bible of the racist right.”

The chapter is titled, “The Day of the Rope” and describes mass lynchings of thousands of “race traitors.”

“The ‘Turner Diaries’ laid out a vision of the US under white supremacist government,” he said. “People would walk outside and literally see for as far as they could see people hanging from street lights in nooses.”

Heidi Beirich, director of the Intelligence Project at the Southern Poverty Law Center, which tracks hate groups and extremists, said some white supremacists advocate genocide and ethnic cleansing. “You would have to forcibly remove people,” she said. “This is cattle-cart stuff. It also shows that their plans aren’t very well thought out. They’re at best aspirational.”

Instead, Beirich envisioned a tyrannical government.

White nationalist Richard Spencer and his supporters clash with Virginia State Police in Lee Park after the "Unite the Right" rally was declared an unlawful gathering August 12, 2017 in Charlottesville, Virginia. Hundreds of white nationalists, neo-Nazis and members of the "alt-right" clashed with anti-facist protesters and police as they attempted to hold a rally in Lee Park, where a statue of Confederate General Robert E. Lee is slated to be removed.

“All civil rights for nonwhites would be removed,” she said. “All political power would be in the hands of white people, in particular white men because this movement is an extremely male and, many would say, toxically masculine movement. They also have pretty retrograde views about what women should be doing.”

She added, “If anything, their vision of America’s future looks a lot like the 1600s or perhaps earlier.”

Experts agree that the possibility of such a society developing in reality is extremely remote. “Real political leadership is so far from reality you aren’t going to find much in the way of Alt-Right policy papers with detailed instructions for different government agencies,” Hawley said.

Segal called it a “dystopian fantasy that has virtually no chance of actually happening.”

“But it’s safe to say that a white nationalist state is not a place most Americans of all races would want to find themselves living.”

How much of a threat do these groups pose?

Trump: Hate and division must stop right now

01:25 - Source: CNN

Because few white supremacists belong to organized groups, it’s difficult to assess the size of their movement and the threat they pose.

The Alt-Right, for example, has no formal organization or membership, and most who identify as such are “anonymous and online,” according to Hawley.

But Segal said the Alt-Right appears to be growing, with more adherents moving from a largely online presence to engaging in events like the “Unite the Right” rally in Charlottesville.

“They want to take advantage of the current political climate, which they feel is unprecedentedly welcoming to their world view,” Segal said. “The outcome of the Charlottesville rally and other events this year will provide them a pretty clear idea of just how welcome their views actually are – and will undoubtedly help shape their plans for the coming months.”

Johnson placed the number of white supremacists connected to groups like the KKK, neo-Nazis, Aryan prison gangs and skinheads “probably in the hundreds of thousands in the United States.”

The Southern Poverty Law Center counts more than 900 hate groups in the US, compared to about 600 in 2000, Beirich said. However, not all of them are white supremacist groups.

Many “Unite the Right” rally participants have latched onto President Donald Trump’s controversial comments about Muslims and Mexicans, according to Beirich.

“They feel validated,” she said. “They feel like all of sudden we can be a part of the political system. The history of the last few decades of white supremacy in this country is that they viewed both the Republicans and the Democrats as a waste of time. In other words, politics was a dead end for them. But that has all changed with Trump.”

Before Saturday’s violence in Charlottesville, former Ku Klux Klan leader David Duke called the “Unite the Right” rally a fulfillment of the promises of President Trump.

“This represents a turning point for the people of this country,” Duke said at the rally. “We are determined to take our country back. We’re going to fulfill the promises of Donald Trump, and that’s what we believed in. That’s why we voted for Donald Trump, because he said he’s going to take our country back and that’s what we have to do.”

Trump, who condemned Saturday’s violence, has sought to distance himself from Duke and white supremacist groups.

“We condemn in the strongest possible terms this egregious display of hatred, bigotry and violence on many sides, on many sides,” Trump said on Saturday.

However, his comment sparked outrage from critics, who said the President should have been more direct and forceful in condemning white supremacy and not equating the violence of counterprotesters with that of hate groups.

Beirich said the far right has inspired violence across the nation, including the fatal stabbing in May of two men who defended a 16-year-old and her Muslim friend in Portland, Oregon, the stabbing death of a young black student that same month at the University of Maryland, and the racially-motivated stabbing death of a 66-year-old black man in New York in March.

“When we took a look at lone wolf attacks inspired by radical right ideas in the last five years of the Obama administration, there was an attack or attempted plot every 34 days in the US,” she said.

ADL research found that people with ties to the far right were responsible for 74% of homicides by extremists in the US between 2007 to 2016, according to Segal.

“Extremists of all kinds are always a threat,” he said, “but when any extremist group feels emboldened, that’s cause for serious concern.”
