Sometimes, RtO has to state the obvious, rather than just restating what other people have observed. This is one of those times.
You may recall that Trump started his extended ruminations about skin color by suggesting that some immigrants from Mexico "are good people." Not many but some.
What, do you suppose, would Trump define as "good people"? How about the Curiels?
I don't know anything about them, except that they left their home country, came into a strange place where they had to start new lives and had a son who was good enough to be confirmed by Congress as a district judge.
Not good enough for Trump, who impugns Judge Curiel's fairness because of his skin.
Trump is a racist and therefore everyone who supports him is a racist.
