You know, the guy who’s been having that same angry conversation about the same fucking thing he’s been obsessed with for the last 5 years and demands that you take his view while going on long monologues and then immediately interrupting anyone who tries to get a word in edgewise? And then goes into a weeks-long suicidal despair if you try to leave the conversation? Any way to deal with that?
Provide no opinions. Pretend like you know nothing about politics. Ask questions. They will argue themselves into a corner, get embarrassed, and then stop talking about it. It requires little effort from you, and they do all the work.
