Brilliantly stated, as always!

One point of clarification: I very strongly suspect that the word "whiteness" to describe all these things actually preceeds some of them, because the origins of "whiteness studies" were back in the mid-80s (https://en.wikipedia.org/wiki/Whiteness_studies).

But rhetorically, the way you introduce it is just fine.

Your third point is perhaps the most important. It is mindboggling how the impliciation (and sometimes the outright statement) has become that if you think that people of all races, not just whites, can be competent in skills needed in a modern society, then you are a racist. I...mean...that's...exactly backwards? Literally exactly backwards?!
