I have a few friends from highschool years that I keep in touch with. One has turned very "liberal" (in the American, low-key holier-than-thou, superficially informed sense) over the years and I cannot talk to him about anything related to the happenings of the world because the PC bullshit that's imported straight from his liberal-"woke" US connections (we're European) will come flooding out and make me snap and tell him to shut his gob if I'm subjected to it one more time.
He's not unintelligent, just never willing to admit error.
