'Bad faith' is the modern authoritarian's favourite excuse for censorship or dismissing comments. Just like 'problematic' it's a vague enough term that it can be easily abused ('dog whistle' and 'gaslighting' are other favourites). You don't have to openly challenge the source material, just question the motives for even asking the question.

Perfect for when you don't have the balls to directly call what the person is saying wrong or bad. Ad hominem 101.
