Don’t engage. They try to get you to argue with them so they can get satisfaction from it. Don’t give the satisfaction. Nod. Say ok. Oh I see. Got you. That’s nice

If they ask questions and wait for your answers so they can attack you, make answers non committing: I am not sure, don’t remember, I forgot.

It doesn’t mean you agree with their BS. You just don’t engage.

So you are just being like a grey rock. You there but not engaging
