I'd focus less on what the so-called "minority" activists are doing and more on why white people in all Western countries believe hating themselves and promoting the agenda of other ethnic special interest groups is their main calling in life. I don't recall seeing Asians, Blacks, Jews, Hispanics, Pacific Islanders, or any other configuration therein promoting the interests of Caucasian people anywhere, ever. Not in rallies, not with picket signs, not on TV, not anywhere. Nor do they campaign against their own people - show me a counterprotest to BLM where there's a single black face to be found?
It's the same phenomenon you see in American politics where whites are evenly divided between two major parties (and the rest vote for the dead-end ones that never get a delegate) but minorites are almost universally in lockstep with the Democratic party. These guys don't have issues with their identity or any guilt complex about their past. Whites do.
