Eh. I don't hate LeBron, hatred seems pretty irrational and it's probably the wrong word to use in the context of almost everything in this thread, even from the folks saying it about themselves. But I get not liking him.
As a person, I have nothing bad to say about him. He seems like a decent husband, father, family member, and he's done good things for various communities. He is probably very arrogant and entitled, but as many have pointed out, that seems to come with the territory and he doesn't seem actively malicious. Maybe he is or has been, but I haven't seen it.
I do not like him as a player for a few reasons. Recognizing he is a great talent and a determinedly hard worker, I've been unhappy with the consequences of his impacts on the NBA with regard to having successfully (and not soley) turning charging for a penalty on the offense, to an almost guaranteed three point play for the offense - at least when he's the guy ramming into set defenders, and the resulting damage that has had on defensive play that has not just damaged the NBA but has trickled down to college ball.
I also haven't liked the way he has chased success from team to team, getting coaches fired and using his influence to force the hiring and firing of team mates. He isn't alone in this behavior, he's just the highest profile - iirc Durant did this as well, and caught appropriate heat for it, but not the Miami kind, that was definitely LeBron. But I can understand the drive to grab the brass ring and maybe the problem has been more about how much sports media has built a circus around every thing he has done and said, trying to create drama and clicks. LeBron and the media have definitely been part of why I lost interest in the NBA years ago. Coincdentally, I was looking at all the play off team rosters a few days ago as a side effect of watching Spencer's laughable ejection video, and realized I have no idea who 90% of the players are on these teams.
Sadly for him, he will never the GOAT in basketball. No matter how many records he eventually breaks, the only thing he'll really be the best at is length of career. He'll only ever be really really good and probably a top five guy at his peak. And that's ok, unless you're a huge LeBron fan - or LeBron himself.
