Rush Limbaugh says that Colin Powell only endorsed Obama because of race. A prominent Maine Republican calls Powell's Obama endorsement racist. Michelle Malkin says it's not because of his race, it's just because of al the black-ass liberalism they share.
Can I point out that Powell spent several years of his life working for the most despised white man in the African American community in several decades? That he's been part and parcel of a party for decades whose continued hostility to black people is rather legendary? I'm sure there's an infinitesimal chance that Powell's deeply buried Afrocentrism reared its FUBU capped head after decades of supporting white Republican candidates for office, but it seems far more likely that for a variety of political reasons related to his built-up credibility and distance from the GOP, he chose to support the hope-and-change Democrat who's looking like a good shot to win rather than the angry old guy with the crappy campaign.
I don't know what you call it when you immediately chalk up anything you dislike about someone to racial differences, but I do know there's a word for it. If only my coarse hair didn't get in the way of all these big thoughts!
