Reductio ad Hitlerum 希特勒归谬法

Reductio ad Hitlerum, also argumentum ad Hitlerum (Latin for "reduction to Hitler", where Hitlerum serves as the accusative case of Adolf Hitler's surname in Latin) is a term coined by German-American philosopher Leo Strauss in 1951. According to Strauss, the Reductio ad Hitlerum is a humorous observation where someone compares an opponent's views with those that would be held by Hitler or the Nazi Party.
