Except none of those shooters have been trans. I looked into it, and I found a youtube channel which does deep-dives on mass killers. For example the Texas shooter, was a girl child on the cusp of functionality, they describe homosexual feelings in their journal, and express fantasies about crossdressing or an alternative identity, maybe some gender questioning, I wouldn’t say they had the language to definitively say either way. Honestly sounded like a confused horny young person with nebulous gay feelings. Either way, that’s not why they did mass murder. They were a mentally ill young person who started using Discord, and then got groomed by the police or the CIA into murdering a bunch of people in cold blood. As far as I know they weren’t involved in the trans community.
