Back in the 2010s, I used to hear people talk about "haters", but it always sounded retarded and delusional at the time, but these days, I stumble across an Andrew Tate video, and the comments are filled with unsubstantiated hate. They literally cannot think of something to attack him for, so they just make shit up, just to hate.
So yes, "haters" are absolutely real, and there seems to be some overlap with Trump Derangement Syndrome type behavior.
Furthermore, there seems to be WAY more hatred directed at someone when they speak the truth, especially if it's an uncomfortable truth.
I normally hate indirect arguments, but when you see someone getting a bunch of irrational hate, and a lot of undeserved pushback against them, you should probably take a second listen to that person.
