I have done this, yes. Your point is well taken: no question there is support for less racism towards black people (including racism amongst black peoples) but there is often deep suspicion about political motives of movements, from the black power 70's to the current Marxist BLM leadership.

Many POC are right wing of course, an inconvenient truth for people who like to think we live in a world of blue (good) versus Red (bad).
