Right: racism isn't a binary thing where either you're racist or you're not. There's a continuum of racism with all kinds of gradations.
I don't think there's any doubt that Trump is more racist than average. I do think there's pretty good evidence that he's not on the extreme end of the continuum. You can go to any mall and find people more racist than he is. And yet he's often portrayed as being on the extreme end -- with people associating him with the KKK and whatnot based on questionable evidence.
You can call him subtly racist and I don't think many would argue. But according to the Google, people are calling him "openly racist" more than three times as often as they are calling him "subtly racist" (about 70,000 results to about 23,000). The "openly racist" charge, however, is not nearly as well supported. I.e., people are overreaching, and the overreaching amounts to crying wolf.
