Lost season finale: Where are the Brothers?

While I enjoyed the lost season finale and the entire season in general, I do have one problem with the show. Where are the black people on the island? How come there are no black people in the Dharma Initiative? It's supposed to be 1977. Are you trying to tell me that there are no black people that could be a part of the Dharma Initiative? The Seventies was big for black people. It was the heyday for blaxsploitation films were black people were arguably the coolest people in movies. Foxy Brown, Shaft, Dolemite, The Mack, Blacula. . . that stuff was sweet. With all those cool black people predominating pop culture, they couldn't put any brothers on the island.

I know why there aren't any brothers on the island. The heat and humidity of the island would do terrible things to the afros and perms that predominated the cool black hair styles of the seventies. A brother can't be seen with a bad fro. That stuff is unacceptable. Brothers do not want to mess up their hair. Plus most black people can't swim (stereotypical, but true), so spending a few years on a crazy experimental island probably isn't that high on the list of things to do.
