It's crazy alright. It's funny though: he's trans, completely TRA-ified, while I'm extremely terfy.

I think you're totally spot-on in believing he was groomed and that you dodged that bullet. I think the same thing sometimes, but with my age instead - there are a lot of women here who believe they would have fallen for the gender cult if they were teenagers right now. It's insidious and preys on some of the most vulnerable people who just want to feel like they are a part of something. I hope your brother finds a way out before doing too much medically.
