I think the worst of Trump's personality traits is his cruelty.

And that goes double for his deplorable admirers who lap it up.

1. Yes, the mocking of the disabled reporter was a perfect example.

2. Cruelty is the point!

"Somewhere on the wide spectrum between adolescent teasing and the smiling white men in the lynching photographs are the Trump supporters whose community is built by rejoicing in the anguish of those they see as unlike them, who have found in their shared cruelty an answer to the loneliness and atomization of modern life."

3. He is a sadistic pig.

He is so insecure that whenever he sees anything that is not like him or that opposes who he is, he immediately moves to crush it in any way possible. His ego is so fragile he cannot stand to have him image or his sense of self challenged by anybody. Someday, someone or many someones will deliver the crushing blow and he will shatter like glass.

4. He straight up likes to hurt people and mock them.

It makes him feel bigger and more important.

5. I think there are so many to chose from.

How can you pick just one?
