If forced to interact with some Maga, I just go full scorn and derisive dismissal. Follow up jokes about flat-earthers and the earth being the center of the solar system. Add in whatever ridiculous thing I can think of. I just keep it up until they don’t want anything to do with me because I’m not buying what they are selling. I’m an asshole though, and I don’t really care if some nutter likes me or not.
