"Argumentum ad Hitlerum," also known as the "Hitler Card," is a logical fallacy that uses Hitler's actions and beliefs as a way to dismiss or invalidate an opposing argument. It's a form of "reductio ad Hitlerum," a tactic of guilt by association that compares someone's argument to Hitler's to discredit it. The fallacy relies on the idea that anything similar to Hitler's actions or beliefs is inherently wrong and therefore unacceptable.
https://en.wikipedia.org/wiki/Reductio_ad_HitlerumReductio ad Hitlerum (Latin for "reduction to Hitler"), also known as playing the Nazi card,[1][2] is an attempt to invalidate someone else's argument on the basis that the same idea was promoted or practised by Adolf Hitler or the Nazi Party.[3] Arguments can be termed reductio ad Hitlerum if they are fallacious (e.g., arguing that because Hitler abstained from eating meat or was against smoking, anyone else who does so is a Nazi). Contrarily, straightforward arguments critiquing specifically fascist components of Nazism like Führerprinzip are not part of the association fallacy.
Formulated by Leo Strauss in 1953, reductio ad Hitlerum takes its name from the term used in logic called reductio ad absurdum ("reduction to the absurdity").[4] According to Strauss, reductio ad Hitlerum is a type of ad hominem, ad misericordiam, or a fallacy of irrelevance. The suggested rationale is one of guilt by association. It is a tactic often used to derail arguments because such comparisons tend to distract and anger the opponent.[5]
