Lots of rappers are on the downlow, TBH. I don't understand how people can label R&B males as gay, but give the benefit of the doubt to negros that kiss other men in the mouth, GTFOH.
There are gays all over the place. Gay rappers are not going to come out and say they are gay because the public isn't ready for one. Rappers are looked as strong, masculine, into women, etc. It is 2011, but I can't imagine a popular openly gay rapper any time soon.
