I’ve got a group of decade-long friends of a variety of political persuasions that I keep on social media because they keep me informed, provide some fairly deep, interesting analysis (a couple have politics PhDs), are much more politically engaged than I am and we get some interesting conversations, whether we all agree with each other or not. You get the of wind-up, but generally it’s good-nature debate.
Two have been binned from FB by me and others in the past 6 months for continued breach of Rule #1, mainly being smug a-holes in the aftermath of the Brexit referendum. They’ve lost friends in real life for the same behaviour, and one of them got laid out by a less even-tempered member of the group on a night out a while back, because he wouldn’t knock the smugness off or change the subject.
It’s not about the point-of-view, it’s about adherence to Rule #1.
