One of my tactics here is to refuse to discuss politics at all, but to encourage any/all discussion of economics and philosophy. One effect of this is to remove lots of trigger words and names, which helps those who feel persecuted or embattled to take a step back. Another effect is you get a much more clear perspective on how they actually operate wrt to belief and evidence.
If you find an economic or philosophical/ethical/moral POV that’s directly contradicting a persons stated political views, don’t just leap on the opportunity to point it out. First realize that the person you’re talking to is probably in a significant amount of psychic pain already from shouldering this kind of cognitive dissonance for decades. Activate your compassion/empathy. This way you can twist the knife better when you do leap on the hypocrisy to try and kill it! Soon you’ll have no friends left and that solves the problem of dealing with political discussions
