The underlying basis for current "conservatives inspire more violence" is largely drawn from clips taken from the manosphere-podcast realm. There is an amount of war hawks always being on the right that predates all of this.
I've seen similar from the left wing, though they don't have good podcast game or modern communication generally.
Manosphere is just the same thing, but more open and direct rather then hidden. Dominance and subjugations are the one and only way to be manly, caring about others is not. Caring is accepted only as part of leaderships role. It is philosophy that alienates. It also leads to violence, partly because you have no real solution to "others dont really accept your dominance" situation and partly because resulting relationships are unsatisfactory anyway.
I grew up around the Dick Cheney type back when northern virginia was a red area in an even redder state. I recall almost no fights between students, much less anyone attacking faculty. Hitting a teacher would have gotten you sent to some alternative school with armed guards.
