I've been staying out of this thread for the most part, but I have to say what bothers me the most is the influence these groups have on kids and young adults, especially in college.
This kid was likely raised in a pretty conservative household. Someone made her a school shooter. They convinced her that the best way to deal with her neighbors not accepting her beliefs, was to shoot their kids.
When radical groups convince fellow believers that violence is the best path, they are a terrorist organization. Trans groups have crossed that line and should be viewed as such.
