There are black voters who support Trump.  Those I know among the men are definitely part of a kind of gender backlash.

But I'd say that, at the very least, Trump voters are "racially oblivious."   Rural and small town (and many other) white voters aren't concerned about the issue.  And, for one reason or another, those Latinos or blacks who supported Trump don't place much store by it either.

BLM made this position more difficult, but it has survived.
