people have been saying this for about a decade, and i really can't figure out why. but here's a little cheat sheet - if it hasn't happened by now, it isn't going to. and you know why it hasn't happened by now? because he's not a racist. i know that's hard for some of you to hear, but he's not. the flow chart in his brain doesn't work that way.
in life, he likes rich people and hates poor people. i can pretty much guarantee you he hates poor white people as much as he hates poor black or brown people. he doesn't want to associate with any poor people and he doesn't want them in or around his buildings. in politics, he likes people who like him and hates anyone who doesn't. it doesn't get more complex than that.
spur-of-the-moment racism is too complicated for his lizard brain. he doesn't have a bunch of n-words on the tip of his tongue and is somehow suppressing them. he doesn't have anywhere near that type of control.
don't get me wrong - he likes racists and he likes white nationalists...because they vote for him.
