It's just that the explanations of why these policies are racist are available all over the place, so if you were open to the possibility, rather than just looking for a place to write a pro-Trump rant, you could have located them by now.

Trump uses what is called dogwhistle racism, described here by someone who practiced it for decades: You start out in 1954 by saying, "Ngger, ngger, ngger." By 1968, you can't say "ngger" — that hurts you. Backfires. So you say stuff like forced busing, states' rights and all that stuff. You're getting so abstract now [that] you're talking about cutting taxes, and all these things you're talking about are totally economic things and a byproduct of them is [that] blacks get hurt worse than whites. And subconsciously maybe that is part of it. I'm not saying that. But I'm saying that if it is getting that abstract, and that coded, that we are doing away with the racial problem one way or the other. You follow me — because obviously sitting around saying, "We want to cut this," is much more abstract than even the busing thing, and a hell of a lot more abstract than "Ngger, ngger." — Lee Atwater, Republican Party strategist
