the answer is really quite simple.
The question was posed by one that lumped all blacks together in one group. We know, but most of America chooses to ignore, that the black lives that don’t matter are the same black lives that ruling blacks consider to not matter.
Even those of the black subculture that don’t matter consider that the lives of their fellows don’t matter. They kill each other with ease and lack of remorse.
The problem of black lives that don’t matter is a black sub-cultural problem not really an American problem. The culture of the controlling black leadership is self centered and corrupt and has no regard for those that don’t matter beyond how their own corruption will be affected.
Those blacks with the political power and ability to make black lives matter don’t. Because, to them, it just doesn’t matter.
It’s true in South Africa. It’s true in Kenya. It’s true in Baltimore. It’s true in Oakland. It’s true in every black-controlled city. The leaders don’t care.
