You can’t have an intellectually honest conversation if there is a bad actor. Intellectual conversations of any kind are predicated on at least two parties doing the mental work necessary to understand the other side, rather than arguing simply for a feeling of being right.
The moment a question like that is posed, it’s no longer an intellectual conversation, it’s one person put in the position of teaching something basic to someone who doesn’t want to learn. No adult owes that to anyone, unless they are being paid to do it.
