Why not do that? If something is unjust, you have ppl in the community who have a big voice and influence on the voters in the area and they should just stay quiet? Whether it makes a world of difference or not, you have to let the powers that be know that you are watching, and you have the ability to make change, and these rappers, social media personalities, etc. hold more sway than the NAACP and civil rights groups with today's youth.
Any time there's a call for black people to make a change in their community for the better and stick together, the opposition comes out hard...
