I find it useful to distinguish between epistemic and instrumental rationality. You’re talking about instrumental rationality – and it could be instrumentally useful to convince someone of your beliefs, to teach them to think clearly, or to actively mislead them. Epistemic rationality, on the other hand, means trying to have true beliefs, and in this case it’s better to teach someone to fish than to force them to accept your fish.
