Ad Hoc

Ad Hoc ("To This") reasoning is where someone fails to understand that there is a difference between argument and explanation. The Ad Hoc fallacy is to give an after-the-fact explanation which doesn't apply to other situations. If we're interested in establishing A, and B is offered as evidence, the statement "A because B" is an argument. If we're trying to establish the truth of B, then "A because B" is not an argument, it's an explanation.

It's a very common sight in justifying edits aimed at any supposedly negative trope, particularly if that edit calls upon things that might have happened to cause the item described.
