I agree that hip-hop and the gay scene don't exactly go hand in hand.
But I think the comment about what homosexual people listen to is a little bit of a generalisation isn't it?? The gay people I know have music tastes as diverse as the general population. I do think a distinction should be drawn between people who are gay, and the "gay scene" as most people perceive it - pride parades, cross dressing, ABBA, etc.
Peace,
