You want to understand, read outside your bubble. Not extremist view, just speeches and responses to direct questions and whatnot.
Some reports may seem extremist because of the shocking response they have to our potus. It's a normal reaction to a fundamentally troubling character that's somehow in power. Somehow its not honest for them to speak out like that, while the candidate gets every benefit of the doubt?
I suggest using those contortionist skills, to understand outrage and shock at the spectacle of an incoherent, largely immoral money-grabber in the White House.
But he is judgmental about everyone and I don't think it is connected to race.
His voters specifically let him say controversial stuff. They like it if it hits sensibilities of his political enemies since it signals his voters that the others just think themselves to be exalted above the allegedly less sophisticated members of society.
Which is funny because his "strong opinions" usually contain much bigotry.

I don't believe he is a racist. He has strong opinions and no fear of hiding them. That is actually a huge draw for people voting for him.
Accusations of racism are mostly political play.
I don't really see how it is self-evident though. What do you think makes him racist? The Obama stuff could be seen as that but I am unsure if it is racism or craziness, but I would tend to think the latter to be more correct.
