Fliers linked to a white supremacist group were found at a third location earlier this week at the University of Maryland in College Park, authorities said.

As first reported in the school’s Diamondback newspaper, fliers were initially found Sunday and Monday at two locations on campus that featured the logo of American Vanguard, a group associated with the white supremacy movement. One read, “We have a right to exist,” and another read, “Defending your people is a social duty not an anti-social crime.”

Late Thursday, a spokesman for University of Maryland police said additional fliers were found on Tuesday at the Lee Building. These fliers included images from the website therightstuff.biz, which is linked to the Daily Shoah, a podcast that promotes white supremacy.

“We’re white and we’re not sorry,” the website says.

University police declined to release images of the fliers. Reached for comment about them, a person answering messages at therightstuff.biz replied in an email: “Russians must have left it there.”

Meanwhile, a U-Md. professor sent The Washington Post other images of the fliers found on campus Sunday and Monday, including one that cites the website of alt-right figure Richard Spencer.

“We will reclaim this country,” says the one that included the citation to the Radix Journal, Spencer’s website. “For our European heritage. For our European peoples.” Another read: “Sons and daughters of Europe! Stand up and claim your birthright!”

Spencer said Friday he was aware of what appears to be a new effort by white nationalists targeting colleges in several states.

“These things are very organic,” he said. “I’m definitely interested in visiting more campuses, and we’re creating a tour. I just do don’t fliering.”

Judith Hallett, a classics professor at U-Md., said she was disappointed by the use of classical imagery, and was troubled lettering on one of the fliers, which she thought deliberately mimicked that of styles popular in 1930s Germany. She also thought the flier’s references to “degeneracy” and “usurious debt” parroted the ways Nazis talked about homosexuals and Jews.

“This is dog-whistle language,” she said.

Meanwhile, UMD Socialists, a socialist group at the school, posted two dozen of its own fliers on campus Wednesday in response.

“American Vanguard is a white supremacist hate group,” one read. “We don’t tolerate racism on our campus.”

The group also released a statement.

“These posters are the latest and most striking example of intolerance on what purports to be one of the most tolerant college campuses in the United States,” the statement said. “It is clear that racists and white supremacists have been emboldened nationally in recent months, and this lone incident is the tip of a very large iceberg that is out there.”

The university issued a statement earlier this week in response to fliers found Sunday and Monday.

“As an institution of higher education, we are committed to the core values of diversity and inclusiveness and do not condone hateful language. Even in difficult situations, however, we honor the right to freedom of speech.”
