I will point out one thing that should be obvious, the shooter was only 22. So it's possible he doesn't have a very baked and stable political ideology. I knew a hard core outwardly homophobic conservative at 17 who came out as gay and did theater by 20. I knew a fairly liberal person when she was about 18 that over the years got to a place where she publicly praised Trump and called COVID a hoax and the vaccine a conspiracy. No idea how that happened, even as I saw it first hand.

Given the situation, it is at least clear he was unhinged if he would get to this point, either way. I would have hoped this would be a lesson for people that people get dangerously moved by angry rhetoric, but a lot of folks are ramping up rhetoric instead.
