For the past 50 years, Blacks have been a voting block of 90% for (D). In the past 50 years (two full generations) very little, if any, progress has been made. I've seen the "Black Lives" matter crowd, who seem to only defend criminals with racist (Its cultural) rants about their own people. It is as if they are saying "Black people are criminals, because they are black". The most racist comments are the ones that indicate that blacks cannot help themselves, and must rely upon the government to give them everything they need, because, well, they can't figure it out for themselves (more or less).
You see people who are actually trying to change the status quo, by giving black people the ability to leave their crappy lives behind, only to be shot down as "racist", indicating that blacks need to stay in their ghettos because well that is where they belong.
Just because something is cultural doesn't mean it is good for the people. Culturally, blacks are still enslaved by white task masters, who let only a few out on occasion when it suits the purposes of keeping the rest of the blacks enslaved to the status quo.
The most racist people I know, are black liberals who hate success using terms like "Uncle Tom" in attempts to drag black people back to the ghetto.
