I hate that some anti-Trump people are over-the-top with their arguments. There is so much true and valid to point at about him, why go too far?
You cannot verify he is a psychopath, but you can verify he cannot admit it when he misspeaks or tweets something wrong. You cannot verify he is a hater, but you can demonstrate he is a self-centered liar who uses dog whistle words to get support from haters.
His supporters do the same with AOC, posting fake information to make her look stupid. Those can be countered by showing her background and education. The same people overlook that Donald hides his college grades.
But it is tough for them to resist calling Trump psychopath when he states he is the best at everything and an expert at everything when he thinks he is telling us something new when telling us Puerto Rico is an island or that he's never heard of a Category 5 hurricane, or that we could nuke a hurricane.
