(JTA) — A group of men wearing large white kippas and tallesim handed out fliers promoting Holocaust denial and hung up cards bearing anti-Semitic canards on a pedestrian mall in Boulder, Colorado.

The fliers handed out at Boulder’s Pearl Street Mall by the men who appeared to be posing as Jews claimed the Holocaust was “impossible.” The men also hung notes on index cards around the mall that claimed “Academia is dominated by Marxist Jews,” Jews run the porn industry,” and “Jews ran the Atlantic slave trade,” the Daily Camera newspaper reported.

The men livestreamed their actions, according to the report.

As of Sunday morning, no reports were filed with police about the fliers, Boulder police told the newspaper.

Boulder was a target of anti-Semitic propaganda in 2018, with the Anti-Defamation League recording 17 such incidents that year. A Jewish population survey of the Denver/Boulder metropolitan area from 2007 — the last time there was such a survey — found that 117,000 people live in Jewish households there.
