To preface, I don't consider myself to be part of either side politically, I think democrats and republicans both have a ton of flaws, but I've been on both sides in the past myself (conservative when I was younger, liberal more recently, and right now not in the middle but not on either side). I think above all else, people hate him because he's just really stupid and acts like he isn't, knowing all his supporters won't bat an eye to it. He could say the most provably, factually, obviously incorrect and dumb shit and the vast vast majority of his supporters are so far up his ass that they'll just roll with it, and he knows that. Obviously Kamala Harris has plenty of flaws, but the difference is that most leftists can observe when a candidate is behaving poorly and call it out. Like most of the people I know and surround myself with are leftists, and when Harris said some shit in support of Israel, not a single person on the left I saw or heard, both online and offline, agreed with it and they rightfully got on her ass about it and didn't let up until the election, and even still now. And if you try to give Trump any shit for anything stupid he says, he can just brush it off like it's nothing because the only people Trump cares about are his own circle, not anybody in the US to any degree unless you have a net worth that's at least 10 digits. And Harris wasn't really any better, but she at least seemed like she wanted to try to fix at least some things, while Trump seems fully confident in promising highly controversial things that will undoubtedly send this country into an even worse state than it already is. And the only reason he'll be able to do it so easily is because he only hires and surrounds himself with people who blindly kiss his ass with every word he says, because he knows that's the easiest method to get his way on everything. Like just earlier today he put on a fucking Fox News reported as the literal Secretary of Defense for the entire country. Is the dude qualified in any way to have a position like that? Absolutely not, and Trump knows that fully, because he knows he's gonna listen to his every word and do whatever he's told to with no pushback or critical thinking. Trump doesn't care about anybody with any sort of qualifications because every qualified person knows he's retarded.
