The fallacy fallacy, or argumentum ad Logicam, is the logical fallacy that if an argument contains a logical fallacy the proposition is wrong.[1] It has the following calculus:
- Argument A supports the proposition P
- Argument A contains a logical fallacy.
- Therefore, P is false

Usage
Correct usage
The fallacy fallacy is not fallacious and is perfectly valid when all possible arguments for a proposition are fallacious - indeed showing that all propositions are fallacies or somehow wrong is the way to disprove something, barring the proposition being unprovable, of course.
However, due to the likely large number of arguments and fallacious arguments (from someone attempting a Gish gallop, for instance) in support of a proposition P, it would be easier to prove not P than to go about disproving P.
Prevalence
This fallacy's use is staggeringly common during internet debates, where pseudo-intellectualism reigns supreme. A person will seek out and attack any logical fallacy you use and dismiss your argument out of hand, without ever addressing the proposition.
