It seems like you might be going through or recently gone through something similar to what I did. I just lost my entire friend group because I was outed as "gender critical". I put that in quotes because the things I said that I lost my friendships over was the simple truth (such as the fact that biological males shouldn't be allowed in women's sports), and to attribute them to a belief system like GC or radical feminism or whatever feels disingenuous.

I dunno man. It definitely hurts. I too am looking into the dark side to try to make sense of what happened, because I truly thought these people were my friends. We knew each other for years - you just don't get over those close friendships overnight. You have to be patient with yourself, and allow yourself to grieve the friendships. I'm talking with a therapist now to learn better ways to deal with it, because my current way of dealing with things is to remain pissed off about what happened. And that's not really helping me any.

Feel free to DM me if you want someone to talk to about all this. Wishing you the best for the future!
