Could you give an example of behavior that "directly" harmed yourself or others which caused you to sever ties?
Politics is almost always indirect, usually with multiple levels of indirection.
I am bi, my "friends" would hate LGBT people, constantly talk how we're pedophiles and so on, and kept voting for parties against equal rights.
People proudly voting for parties and policies that demonise trans people, of which I know many. I cannot be your friend in good conscience if you're willing to destroy the lives of my other friends.
