I'm linking why most mass shooters are white.

Due to the fact of a recent revelation involving a Nazi targeting children. They're white because the neo Nazi groups target children from young ages on private chat rooms. Back in the days of Nazi Germany it was likely outside of schools. Well schools are still prime targets today as statistics show that but mass shooters are mostly white because these same shooters are likely targeted by Nazi groups at such places. They are vulnerable and reach out online then are taken advantage of by white child predators and then eventually radicalized into doing something.

They just happen to be white because the govt is also has a heavy white Nazi presence and has no motivation to stop it so the radicalization happens when they're young.

I also wouldn't doubt if white Nazi leaders were exposed to the same thing. So that's why mass shooters are primarily white.
