Why should blacks be silent

it seems to me that blacks are being silent about the issues we care about while all the other races are going about getting theirs, if you look at the renewed attacks on "black power" you can see that the folks that hate our people are busy. Where are the voices of change for us? Rev. Al is getting old and Jess Jackson is not effective. who are the new leaders of black America? why are they so silent? i have to depend on Kieth Olbermann and the rest of the MSNBC folks to speak for my point of view. all the black leaders i think are trying not to upste white folks so Barrack can have a better chance of making it in the White House. if this not the case then why are we so quiet about our pain? Obama can take care of his dreams while we are still living the American nightmaire.
