I don't know if this person is saying they disagree with their friends on politics or if the vitriol in their friends' political speech is harmful to them. If the latter, I sympathize: most political conversations today are so filled with hate that "direct harm" to listeners is not unreasonable to claim.
Most of the time, when someone's said something like "their politics directly harm me", it's something like "the policies implied by the positions this guy's professing (or directly advocated for) would have bad effects for me". Could be wrong, obviously- it's a pretty vague phrase. But I'm sympathetoc- if they hold a certain position, and cultivate a certain identity, and that makes certain other positions disgusting to them to the point they cut out friends- good for them, I guess, and I get that being alone isn't pleasant. But that's the price you pay for being the kind of person who responds that way.
I guess presumably he would have gotten new, less offensive friends if the governments of the world hadn't made it illegal.
(How'd he end up friends with these people in the first place?)
