You can't talk to them person to person. That type of persuasion works in matters when the other person is operating in the cerebral realm of logic. The problem in politics is that we're operating in the realm of identity, and you cannot reason somebody out of a matter of personal identity, because the brain treats threats to personal identity the same way as physical threats. Especially when it is a closed belief system that defines politics as tribal combat, veracity as irrelevant, any information that comes from outside the tribe as per se objectionable, and agreement as a failure of will.

Basically, the psychological research funds that you have to take them out of the Q/MAGA bubble, and surround them with people with diverse views. It can't be done in online forums. I've tried. If you listen, you just get regurgitated talking points, and if you ask questions that start to make them think they abruptly disengage.
