appeal to triviality 

A logical fallacy where someone involved in an argument says the issue in question being argued over "doesn't really matter" in an attempt to shame their opponent into giving up so that their side can push their agenda unopposed.

This fallacy is easily countered by telling the person doing this argument to shut up and go away if they don't actually care.

Person 1: "Why do you care so much if the space marines in Warhammer 40,000 are female anyway? It's just toy soldiers, stop being such a whiny incel over nothing!"
Person 2: "Appeal to triviality. If you didn't actually care about this stuff then you wouldn't even argue about it in the first place."
