A black political party would be no more accountable to black people than any other entity claiming to represent black interests. Lobbyists, organizations like the NAACP & BLM, and yes, this theoretical black political party, all need money to operate, and by extension are subject to the same problems of accountability. So unless you can explain how this political party could exist and grow without financial support I'm not seeing how it would be any different.
Black political problems really come down to 3 things. One we are too thirsty for some charismatic speakers and leaders to cajole us into getting organized. Latinos, Jews, LGBT all get shyt done without political parties or their own versions of MLK. Two we waste too much fukking time talking about what we wish we could do instead of making the most of what we can do. I.e. you want a black political party, but either don't realize or intentionally dismiss the political leverage we aren't utilizing now. And three we don't have any kind of collective agenda. Lot of bad ideas floating around. nikkas still talking about reparations
We need to do like the Jews. nikkas play too much. Too much chatty chatty not enough action.
