I actually agree with your thesis, that portraying the opposition as an existential and real threat to everything you hold dear creates an environment where stochastic violence is inevitable. At least, I think that's your thesis.

However, your article ignores all the violence against Democrats, of which, there is plenty. It also ignores the fact that the Republican ideologue industry is rife with decades of people claiming the same against Democrats, often using even stronger language. Democrats are literally described as "demons" and such.

This puts your thesis at a crossroads of contradiction: Either you are admitting that Democrats are also targeted due to the same rhetoric or that they are not. Well, if they are, then the whole vibe of your title is off. Democrats ARE targeted, too. Or, they are not and your thesis on the mechanism on why Republicans are always targeted instead of Democrats must be false.
