I think this can go too far in the opposite direction. Sometimes an entirely foreign concept sounds like bullshit at first contact. Or someone speaking a bit incoherently–good people can get confused or get struck by a thunderbolt of stupidity from time to time.

So ceteris paribus, yes, cut off bullshitters. But context matters. If a friend of a good friend is striking me as stupid, I'm going to make damn sure that's what's happening versus me misunderstanding them (or catching them at a bad moment).
