You and I and everyone here knows it's not caused by LGBT people. But commentators on the right have been pointing out all the problems that men face and point the finger directly at LGBT, Feminists, and POC. Just like how the Nazis did the Jews. Yeah it's not true that it's LGBT people's fault. But thanks to propaganda he now believes that's true. It's up to OP now to decide whether this friend is worth keeping and help deprogram him, or whether it's time to leave him and move on. And that's a deeply personal question that OP will need to decide. There isn't a right or wrong choice it's just whether it's worth the effort of deprogramming them or not.
