The question is not if I disagree with people or politics. I.e. people can have different opinions about social supports, wars, abortion, and many other issues, I accept that.
The problem with many losers and stupid people is, that they don't care about the truth and reality. I.e. if Trump would say something like: I lost the last election, and now I will work harder to win your trust so that I win next time.
That would make sense. I still wouldn't like him, but I would accept that he fights for his believes.
But Trump still denies reality on so many levels. And his followers should know that he is lying all the time. Why do they support a serial liar?
