The "not all Muslims are terrorists" fallacy

[Angrboda]

There's also the fallacy fallacy. This is where someone has learned the names of a load of logical fallacies, but doesn't understand them properly and raises them as incorrect objections.

Argument from fallacy is the formal fallacy of analyzing an argument and inferring that, since it contains a fallacy, its conclusion must be false. It is also called argument to logic (argumentum ad logicam), fallacy fallacy, fallacist's fallacy, and bad reasons fallacy.

Fallacious arguments can arrive at true conclusions, so this is an informal fallacy of relevance.
