You ARE a fascist if you support labor unions.
Hitler and Mussolini both came to power with the help of labor unions. Communism (class-envy fascism) depends on labor unions to hold on to power.
What is fascism but one-for-all-and-all-for-one fanaticism? Look at the Italian Fascist symbol: a bundle of sticks surrounding an axe. Is there a better metaphor for unionism?
