“Not Stolen. Conquered,” a flier found in a music building at San Diego State University read. “Your professor is scared of this book,” read a sticker outside a building at New York’s Baruch College, referring to a work by white nationalist Jared Taylor.

White supremacist propaganda on college campuses is on the rise, according to a report by the Anti-Defamation League. The nonprofit found 292 occurrences on campuses located in the District of Columbia and 47 states, a 77 percent increase compared with the 2016-2017 school year. The ADL relied on news reports, community complaints and extremist sources to complete the report, according to Oren Segal, director of the group’s Center on Extremism.

The propaganda typically appeared on stickers, posters, banners and fliers, and it varied from “veiled white supremacist language to explicitly racist images and words that attack minority groups, including Jews, Blacks, Muslims, non-white immigrants, and the LGBTQ community,” the report said.

“College campuses and their communities should be places for learning, growing and the future, not close-minded racism and hate-filled rhetoric from the past,” the ADL’s national director, Jonathan Greenblatt, said in a statement. “We’re concerned to see that white supremacists are accelerating their efforts to target schools with propaganda in hopes of recruiting young people to support their bigoted worldview.”

The report highlighted Identity Evropa, an organization founded in 2016 that recruits college-aged people though banners, stickers and online propaganda.

The group was responsible for 48 percent of reported incidents in the past two years, the report found. In January, members posted fliers over historically significant African American images outside the black studies department at the University of South Carolina at Columbia, the report said.

“The ADL is clearly reporting in error or negligence, as the blanket allegations reflect neither Identity Evropa nor any statement from a current representative,” group spokesman Sam Harrington said in an email. Harrington noted the group is “seeking a better future for European Americans” and does not advocate for “supremacy, violence or illegal activity.”

“The ADL, and organizations like it, are attempting to stifle free debate and will continue to lose trust with the thinking public,” he said.

The ADL describes Identity Evropa as a white supremacist group that avoids recognizable language and imagery on its symbols in an attempt to enter mainstream conservatism.

Members were present at this year’s Conservative Political Action Conference and last year’s Unite the Right rally in Charlottesville. The night before the protest turned deadly, participants chanted their popular mantra, “you will not replace us.” The chant, Harrington said, references people “who believe there is something to be gained from demographically replacing European Americans through immigration and globalization.”
