One of my old MMO friends came out as a MAGA after a year of raiding together. Tbh, it kind of didn't matter since we were killing shit in a game and it just didn't come up unless I was mentioning watching certain political satire shows. He wasn't an outstanding guy, but I've played with much worse people and would still consider him a friend.
Don't play with him anymore, but that was because of his other terrible life choices, going all in on playing League.
A guy at my D&D table went that way. Kinda glad the nights he doesn't come tbh. Just feel dirty associating with someone like that outside of work.
Oh hi it's you. My wife is an immigrant, my sister-in-law is trans, I'm an angry atheist and my life work is in the environmental sector. You hate my wife, my religion, my sister-in-law, and my career. Yet here I am spending time with you freely.
It helps that in my case, the guy was mostly just enthralled in the cult of personality. Union guy, not religious, etc.. If someone you know was part of a cult, you can either express concern and try and help, or leave them be. I ended up doing the latter, especially since back then maga was still a new term.
