I've seen plenty of actual death calls for gay and trans people. A Texas pastor even talked about lining up gay people and shooting them. Or that trans people should be eradicated completely. Donald Trump himself even reposted a tweet where the first sentence was, "the only good democrat is a dead democrat".
Can't say I've seen nearly anywhere near as much about republicans. Not as many people nor prominent figures. Sure, they're called corrupt and maybe stupid or harmful or other words but I don't remember Biden endorsing "the only good republican is a dead republican".
Obviously if someone says that republicans should all die, then yeah. That's just as bad. And it does happen. But not nearly as often as minorities get targeted. You're still right. Dehumanizing is absolutely not good and you should judge each person as an individual. But just realize there's quite a bit of difference in scope.
