A famous neo-Nazi who co-runs Daily Stormer website, may actually be Jewish according to his mom.

Andrew “Weev” Auernheimer recently said Jewish children “deserve to die,” has Jewish relatives on “both sides of his family,” his mother told Newsweek.

32-year-old Auernheimer said on Radical Agenda, hosted by Christopher Cantwell; “If you don’t let us dissent peacefully, then our only option is to murder you. To kill your children. To kill your whole families. There is only one thing absent free speech that we can do to express our dissent and that’s to slaughter you like dogs, and you’re gonna have it coming and your children will deserve to die.”

The interview was published on Daily Stormer, which primarily posts Jewish conspiracy theories and memes celebrating physical violence against Jews, women and people of color.

“We have been very, very patient,” he said. “What can we do if we can’t even post a n—-r joke or a Jewish joke on the Internet? There’s only one thing left and maybe they should be very, very wary of what they’re asking to have happen to them, if they won’t let us have that.”

He narrowed in on specific targets later by saying that retribution should focus on, “The top class [of Jews]. The most Jewish Jews.”

“Nobody has gone after these kinds of Jews,” he added.

Newsweek has been unsuccessful in contacting him. His Jewish heritage  was first reported by Gawker in 2012, though Auernheimer denied the report.

However, his mother has confirmed it. Alyse Auernheimer told Newsweek that she had been estranged from him for over a decade.

“He doesn’t like us,” she said, adding that her son comes from a “large, mixed race family” with Native American heritage, and that he most certainly has Jewish lineage “on both sides of his family.”

White nationalists have been discussing the rumors about his heritage—which may not end well for his credibility in the movement.

“Jews cannot be part of the white nationalist movement, just as a white man can’t be a part of a black-nationalist group like the Nation of Islam,” Matthew Heimbach of Traditionalist Worker’s Party, a white nationalist group that attended the rally in Charlottesville, told  Newsweek. Any discussion of Auernheimer’s family being Jewish on both sides would be “something interesting to a lot of people,” he added.

Cantwell, the owner of Daily Stormer defended Auernheimer – “If that’s true, he wouldn’t be the first self-hating Jew,” Cantwell said.
