We are talking about a history where: a) A decision to not occupy a defeated country was made because they were impure/non-white (Mexico)... [I don't think I have encountered a similar historical example. I will spend some time looking/reviewing just in case I am forgetting some similar situation.] b) Called Germans and Finnish immigrants "non-white":

Italians and Greeks faced the same treatment. Everything and everyone had to be assigned at some class/color. The wikipedia article goes even more in depth about the issue that also posed for Asians in the U.S. which is a whole lot different rabbit hole, and which I am still confused about.
c) Gun control and argumentation started because of racism. NRA actually did support gun control at one point: when the Black Panthers tried to exercise their right to bear arms. And when Reagan introduced the Mulford Act in response, evidence shows it was enforced based on race.

And going way back: Black Codes were a big part of Jim Crow measure: everyone could have a gun; unless you were "black." (Or other undesirable.)

There is the claim that the 2nd amendment was enacted to ensure slaves wouldn't revolt. Not sure yet how much weight one should place to that claim; but the world history supports such considerations. [Review cf. Spartans for instance or the Japanese class system.]
