demagogue: a political leader who seeks support by appealing to popular desires and prejudices rather than by using rational argument

hatemonger: a person who kindles hatred, enmity, or prejudice in others

"When Mexico sends its people, they're not sending their best. They're not sending you. They're not sending you. They're sending people that have lots of problems, and they're bringing those problems with us. They're bringing drugs. They're bringing crime. They're rapists. And some, I assume, are good people."

"In the Middle East, we have people chopping the heads off Christians, we have people chopping the heads off many other people. We have things that we have never seen before -- as a group, we have never seen before, what's happening right now. The medieval times -- I mean, we studied medieval times -- not since medieval times have people seen what's going on. I would bring back waterboarding and I'd bring back a hell of a lot worse than waterboarding."

"I think Islam hates us. There's a tremendous hatred. We have to get to the bottom of it. There is an unbelievable hatred of us."

I would say demagogic hatemonger is a perfectly accurate description of Donald Trump.

If anything, I'd call that a charitable description, and definitely not as strongly worded as most would write.

Hardly. Demagoguery appeals to people's emotions and prejudices, rather than rational argument. There can be no doubt that Trump takes exactly such an approach. And he has vocally encouraged violence and identified specific groups to serve as targets, based on race and religion. That description is entirely apt.

I really hope you're taking issue with some subtle issue with the phrasing, rather then the intent.

With regard to the intent, I think it's too weak, if anything. "Sociopathic demagogic hate-monger", maybe.

Along with the lazy Nazi comparisons.

It's also redundant. Demagogs === hate-mongers.
