People want to root for a winner, but if you're too good then it's unfair and they're a bunch of all-stars? That makes no sense. We've all seen all-star games that weren't about good basketball. But the Warriors know how to play as a team. It'd be one thing if KD didn't fit, but he does. And to say KD can't make that move is to deny him the freedom that we all deserve. And what are the motivations for that, exactly?
The hatred of KD and the Warriors is as irrational as much of the political hatred we see. Voters may have started with some kernel of truth, but their rational reasons turn into animosity and they forget the reasons that they disliked (or liked) someone in the first place. It becomes "your guy" vs. "my guy," and eventually, "Your guy is basically Satan (even though I can't logically explain why)," and "My guy may not be an angel, but he's a hell of lot better than your'n." Hyperbole. Irrationality.
