EDIT: I'm removing small details so people can focus on the topic at hand. This is not a troll post. I don't have a problem with what my friend's beliefs are. I have a problem with his attitude. I have a problem with the fact that his beliefs are "beliefs" that he blindly accepts not opinions that should be debated over. I have a problem because this is so not like him. I have a problem with his descent into bigotry.
Recently had a series of uncomfortable interactions with a good friend.
The guy has his own prejudices (don't we all?) and is a bit of a difficult character but I've never been this upset. Dare I say, I feel traumatized by the recent interactions.
He casually brings up super general and catchy but false statements (ie. Statements like "All cops are Fascist assholes"/"Rich people are evil" if you're a far leftie or "all liberals are depraved satan-worshippers"/ something something super anti-Semitic if you're a far-rightie). Whenever I ask him to explain, he always brings up some anecdotal examples.
Whenever I try to tell him what he perceives may be far from the truth and try to convince him to really think about it objectively, it seems like he can't even try to be open-minded. He seems to have already made up his mind and is just parroting whatever narrative he believes in. Whenever I try to bring up other view points, he is very dismissive and just tells me "shut up, you don't know anything".
He claims that he's believes in certain "isms" but whenever I ask him to explain what those mean or what the fundamental principles are, he can't give me a straight answer. This slow decline in critical thinking seems to have started since he joined some politicial activist group. I read into this group and it looks like a cesspool of ideologues who don't do much reading besides "literature" of their own beliefs that perpetuates this weird ideological circle jerk.
I've met idiots who are on Twitter 24/7 and have nothing intelligent to say about the world. But my friend used to be an intelligent and quick witted person. The decline in his critical thinking and listening abilities just pains me greatly. I don't know if I should feel angry, concerned, or both. It's even impacting my mental health a bit and I can't stop thinking about it for some reason.
Has anyone gone through a similar experience? And how did you handle it?
