After Anne Frank's stepsister and Holocaust survivor Eva Schloss compared Donald Trump to Hitler in a Newsweek op-ed this Wednesday, many neo-Nazis spoke out online to endorse and defend Trump.

As ATTN: has reported, white supremacist Trump supporters are particularly fond of the meme format. While some accounts answered 86-year-old Schloss with positive Trump-Hitler comparisons, others tweeted attacks on uninvolved Jewish public figures, including writer, filmmaker, and political activist Susan Sontag.

This isn't the first time Trump has been endorsed by white supremacist groups. Andrew Anglin, the publisher of the neo-Nazi website The Daily Stormer, publicly endorsed Trump in December, writing, "Heil Donald Trump – THE ULTIMATE SAVIOR."

The Republican front-runner's twitter following further reveals that there is a disturbing underbelly of unapologetic racists supporting his presidential bid, and Trump has recently come under fire for retweeting a white supremacist Twitter account.

Schloss, an Auschwitz survivor, said Trump "is acting like another Hitler by inciting racism," and that "If Donald Trump become the next president of the U.S. it would be a complete disaster."

Her comments have drawn mainstream media attention to Trump's growing neo-Nazi following, a hate group that agrees that he may be the next Hitler and support him for this very reason.

"At this point, if you still don't support Trump, I'm seriously questioning whether or not you're [a white nationalist]," one commenter posted on a white supremacist forum thread called "Stormfront" Monday evening.

Another poster replied:

While white supremacist groups and their online communities are hardly a new phenomenon, Trump's five-months-long lead in the polls and the upcoming caucus bring alarming hate speech into the public sphere and reinforce Schloss's fears about the political reality of a Trump presidency.
