Here is Andrew Sullivan in Salon on Belafonte. Although the whole thing is worth reading, here is a good paragraph.
"But this attempt to reduce Colin Powell, an accomplished soldier and respected diplomat who wields more influence than any African-American in history, to
a crude caricature of a racial stereotype should be called what it is. It’s racism. And what does Belafonte get from peddling in such bigotry? He gets an evening devoted to lionizing him Thursday night by a group that considers itself progressive: the Africare annual dinner. As an extra twist, this demagogue has the power to demand that Condi Rice, the most powerful African-American woman in the history of American government, be disinvited as a condition of his appearance." Clarence Page also beats up on Belafonte.
