An anti-Nazi movie from World War II went viral over the weekend after a white supremacist rally in Charlottesville, Va., turned violent.

The film, “Don’t Be a Sucker,” was produced by the U.S. War Department in 1943 to warn Americans against fascist language and calls on them to denounce such behavior, according to Business Insider. It was eventually released in 1947.

The two-minute-long film opens with a man yelling about “foreigners with money” and “negroes holding jobs that belong to me and you.”

“Now I ask you, if we allow this thing to go on, what's going to become of us real Americans?” he yells.

One man in the crowd begins to agree with the speech before he hears the Freemasons, a group he belonged to, being attacked.

“In this country we have no other people, we are American people,” another man in the crowd says.

The video was first posted Saturday by anthropologist Michael Oman-Reagan on Twitter, with the caption, “1947 anti-fascist video made by US military to teach citizens how to avoid falling for people like Trump is relevant again.”

A man with alt-right ties on Saturday was charged with second-degree murder after allegedly driving his car into a crowd of anti-fascist protesters. One woman, Heather Heyer, was killed in the attack.
