It is a fallacy of irrelevance
Ignoratio elenchi
Ignoratio elenchi is the informal fallacy of presenting an argument that may in itself be valid, but does not address the issue in question...

 where a conclusion is suggested based solely on something or someone's origin rather than its current meaning or context. This overlooks any difference to be found in the present situation, typically transferring the positive or negative esteem from the earlier context. Hence this fallacy fails to examine the claim on its merit.

The fallacy most often assumes the form of "Hitler (or the Nazis) supported X, therefore X must be evil
Evil
Evil, in many cultures, is a broad term used to describe what are seen as subjectively harmful deeds that are labeled as such to steer moral support. Evil is usually contrasted with good, which describes acts that are subjectively beneficial to the observer. In some religions, evil is an active...

/undesirable/bad,". For example: "Hitler was a vegetarian, so vegetarianism is wrong." The tactic is often used to derail arguments, as such a comparison tends to distract and to result in angry and less reasoned responses.

Fallacious nature of the argument


Reductio ad Hitlerum is rationally unsound as guilt by association (a form of association fallacy); it illogically attempts to shift culpability from a villain to an idea regardless of who is espousing it and why. Specific instances of reductio ad Hitlerum are also frequently likely to suffer from the fallacy of begging the question
Begging the question
Begging the question is a logical fallacy in which the proposition to be proved is assumed implicitly or explicitly in the premise. Begging the question is related to circular argument, circulus in probando or circular reasoning but they are considered absolutely different by Aristotle...

Those policies advocated by Hitler and his party which are generally considered evil are condemned in and of themselves, not because Hitler ordered and enforced them. For example, genocide

 are considered evil on their own qualities, while Hitler is considered evil largely because he advocated them. A common example of the fallacy in action is, "The Nazis favored eugenics

 debate over eugenics is not directly connected with Hitler or the Nazis in particular; both eugenics and criticism of it considerably predate Nazism. Used broadly enough, ad Hitlerum can encompass more than one questionable cause fallacy type, as it does in the eugenics example, by both inverting cause and effect and by linking an alleged cause to wholly unrelated consequences. Hitler was fond of dogs and children; however, to argue that affection for dogs and children is evil on this basis is hardly convincing.

The argument being false, however, does not prove that X or its supporters are not evil (assuming so would be another fallacy, namely affirming the consequent
Affirming the consequent
Affirming the consequent, sometimes called converse error, is a formal fallacy, committed by reasoning in the form:#If P, then Q.#Q.#Therefore, P....

). Moreover, recall that the argument is false in itself, no matter whether X is actually good or evil. So, "Hitler killed human beings, therefore killing is wrong", is nonetheless a fallacy, however truthful the premise and conclusion may be, because there is no logical connection between the two. It would be akin to "I wear trousers, therefore the sky is blue". This sentence is logically faulty, even if the speaker does wear trousers, and the sky is blue that day.

Various criminals, controversial religious and political figures, regimes, and atrocities other than Hitler, the Nazis and the Holocaust can be used for the same purposes. For example, a reductio ad Stalinum could assert that corporal punishment of wayward children is necessary because Joseph Stalin

 "The Fascists also made the trains run on time" might implicitly reference the reductio ad Hitlerum.

Many of Hitler's qualities and talents were admirable if seen in isolation. He is generally considered an excellent orator and a political organizer of first rank, despite his use of those talents to further a program of genocide, aggressive warfare, and other atrocities. It must be remembered that not all arguments involving Hitler or Nazism are reductio ad Hitlerum, although they may be otherwise fallacious.

's 1953 book, Natural Right and History, Chapter II:

In following this movement towards its end we shall inevitably reach a point beyond which the scene is darkened by the shadow of Hitler. Unfortunately, it does not go without saying that in our examination we must avoid the fallacy that in the last decades has frequently been used as a substitute for the reductio ad absurdum: the reductio ad Hitlerum. A view is not refuted by the fact that it happens to have been shared by Hitler.


The phrase was derived from the better known (and sometimes valid) logical argument called reductio ad absurdum

Mark Leibovich in the Washington Post described the outcome as follows: "It prompted yet another episode in what has become a familiar Kabuki in American political discourse: Someone invokes the behavior of Nazis in some non-genocidal context. This is followed by an outcry (in which members of the opposing party are "saddened"), condemnation from the Anti-Defamation League, futile attempts by the speaker to "clarify" his remarks, repeated calls for him to apologize and, inevitably, some acknowledgment of regret, often tearful."
