Don't Be a Sucker is an anti-fascist propaganda film produced by the United States Army Signal Corps. It follows a Freemason, Mike, who buys into the prejudiced beliefs of a demagogic street speaker until the speaker denounces Masons. A European refugee then speaks to Mike about how the same prejudiced beliefs led to the rise of fascism in Germany. The film argues that both majority and minority groups are harmed by fascism, and that Americans must unify against fascism regardless of race, religion, or national origin. Don't Be a Sucker saw a resurgence in popularity after the Unite the Right rally in 2017.
