I bang on a lot about not saying things like "this person is a threat to democracy" and other such apocalyptic statements. This right here is a perfect example of why: when you steep people in a culture that tells them someone is (or their ideas are) an existential threat, eventually someone is going to be the right level of scared + unstable that causes them to kill people to try to defend their way of life.
If you find this horrifying (and I hope you do, because there can be no moral justification for celebrating murder), then I encourage you to really think about whether we would not be better off without such extremist language poisoning people's minds. We have to try to stop escalating, or the cycle is going to destroy our society.
