Because sometimes what the masses want isn't always what's best for all. About toxic people who want to get reactions out of you. About loose-fitting racial categories. You're either black, white (incl. Fareast Asians & Arabs), Indian/south Asian, Australasian, Amerindian or a mixture of any of those groups. We have not discovered green & purple aliens yet. In the modern world, a black man can't afford to be just a hut-dwelling, spear-throwing, hunter/fisher/farmer. We need to know modern technologies & trends to prevent ourselves from going extinct no matter if we deliberately choose to be hut-dwelling, spear-throwing, hunter/fisher/farmers.
