Idk man conservatives in recent history have a pretty consistent track record of assassinations and assassination attemps on liberal and leftist politicians in the US based on their politics. Tommy Burks was outright killed by his Republican opponent less than a month before the election (Burks was one of the most conservative Democrats at the time, but he was certainly killed by a lot more conservative Republican), Clementa Pinckney (targetted in a white supremacist shooting at a primarily black church that he was the pastor of), Gabby Giffords (shot in the head by an anti-government right-wing conspiracy theory consumer).
When Republican politicians are killed now, it's pretty much only by personal enemies/drama that is unrelated to liberal or leftist politics, or by schizophrenic/criminally insane people who also weren't doing it over politics. Like Linda Collins (her friend killed her after being confronted for stealing money), Mike McLelland (he was killed by a former lawyer who's theft case he prosecuted). Hell, even Ronald Reagan was shot over an actress, not over the guy's personal political views. Ironically, Republican John Roll was killed by the right-wing terrorist targetting Gabby Giffords, he was caught in the cross-fire. I don't think there's even an in-office conservative Republican politician that was assassinated by a Democratic rival this century, or even a single instance of a conservative Republican being assassinated by a liberal over politics recently.
I want you to think of how frequently you hear of terrorist attacks which were committed in the name of white supremacy, christian nationalism, dicrimination against LGBT, or some other far-right bullshit, and then think of how frequently you hear of terrorist attacks committed in the name of progressive beliefs like, oh idk universal healthcare and better public transport. it's gotta be at least like a 20 to 1 ratio, and that's me being conservative with the amount of conservative attacks.
