It's the negative winning out over the positive. If you genuinely want things to get better you have to stop thinking about how they won't.
If you can't, you're part of the reason why things won't improve. You want your negativity (or your ego) to be proven right.
That's a good general point; if you find you dislike someone's POV or behavior, and you're not simply being tribalistic, you should be thinking along the lines of, "what do I want this person / group to do differently?"
