A racial group is a racist group. BLM is a racial/racist group and they get away with it because live in black-chauvinist world, as inexplicable as that may seem to some.
The old pre affirmative action/black power world where blacks had to pay the consequence for their actions as both individuals and cultures, just like everybody else was much fairer and better.
Blacks as slaves was merely a direct result of Africa's especially slave-oriented culture which existed from ancient times to the present day. Nothing particularly wrong with it, but slavery = black culture.
