We need to learn how to argue with fallacies.

Appeal to Authority argumentum ad verecundiam (also known as: argument from authority, appeal to false authority, appeal to unqualified authority, argument from false authority, ipse dixit) Description: Using an authority as evidence in your argument when the authority is not really an authority on the facts relevant to the argument.  As the audience, allowing an irrelevant authority to add credibility to the claim being made.

Proof by intimidation is a jocular phrase used mainly in mathematics to refer to a style of presenting a purported mathematical proof by giving an argument loaded with jargon and appeal to obscure results, so that the audience is simply obliged to accept it, lest they have to admit their ignorance and lack of understanding. The phrase is also used when the author is an authority in his field presenting his proof to people who respect a priori his insistence that the proof is valid or when the author claims that his statement is true because it is trivial or because he simply says so.
