I wouldn’t change a thing about Trump. He is civilized. This speech would be directed at those who are not.
The guy in Ferguson, for example, who attacked a cop in his patrol car. That is animal behavior. Yet no one is calling him responsible for what happened to him.
I sympathize with you on the destruction of civility -- or rather, the destruction of our ability to have reasoned discussions about anything of substance -- but the ones "who are not" are beyond the reach of any sort of speech you describe.
