Being conservative in and of itself does not make someone a sell-out.. You know who I consider sell-outs?
Those African-American men and women who sell drugs in our communities
Those professional athletes/entertainers/business people who are making PHAT $$$ who do absolutely nothing to give back to the community.
Black folks who feel like if they speak to the (usually Black) custodial worker in the office then their white co-workers will realize

that they are black too!!
Those Black folks who think the white man's ice is colder!
Black entertainers who feel absolutely no responsibility for the filth that they put on TV/in records, but are all about the bling-bling!
Mothers or Fathers who abuse/neglect/don't support their black children
Black business owners who sell inferior products at inflated prices then EXPECT you to support them!
ALL SELL_OUTS!!!
Just because a person has idealogical differences does not mean that they are sell outs. Example: some blacks do not believe in afirmative action. They believe that the best way for blacks to reach equality in this society is for them (us) to delay gratification, open our own businesses, take advantage of SMB loans, etc. Now I don't necessarily think that someone who believes that, no matter how misguided I think they are, is a sell-out
