His whole shtick is anger, grievance, and vengeance...

I will tell you why you support him... it boils down to that need of yours to be the victim... he plays to it and cajoles you to be angry about your victimization, and once you are angry and irrational he points to some group of people- usually powerless people, and tells you 'THEY are the ones victimizing you!!!'

Trump, just this weekend in Georgia:

"We're all victims. Everybody here, all these thousands of people here tonight, they're all victims. Every one of you."

THAT is his appeal to those that support him-

'Its not YOUR fault you haven't gotten where you want in life- it THOSE PEOPLE that are holding you back, you should be angry at THOSE PEOPLE for what they have done to you! Any atrocity you have dreamed of committing is justified against THOSE PEOPLE.'

And when you turn away to yell at THOSE PEOPLE, and demand something be done about THOSE PEOPLE, and attack THOSE PEOPLE he just laughs and steals a few hundred more billions from the nation to distribute to himself and his friends.

Trump's anger is all about him, it is directed at people that have wounded his ego, or it is directed at innocent people simply because it suits his political needs.

My anger is all about what has been done to those innocent people in your name.

YOUR anger should be directed at what you allowed him to turn you into.
