Bad Faith
Not my faith

Why would you be bothered by people making fun of you for not wanting to argue with bad faith actors? The whole premise is that there's literally nobody no there that's saying things in good faith - there's no discourse to be had and as such, trying to argue anything is pointless. What jokes can you even make about that?
