Well that's a complicated issue. Every equality movement has its various components, each viewed differently by one another and "outsiders." As far as black equality, you can look at some of the major figures throughout history: Du Bois, Booker T., Douglass, MLK, Malcolm X, Black Panthers, etc., etc. I mean, that's a diverse group of ideology and tactic.
NOw you might look at the Black Panthers or X and say "they didn't do much to further their cause"...but by whose standards?
Either way, I suspect you're right. They aren't furthering their cause by being lewd and in-your-face in that particular instance. But until I see an equal emphasis on getting straight men to stop disrespecting women with their lewdness and suggestive comments, I honestly don't care if a gay man does the same to other men.
I'm an adult. If I get hit on by a man, and I have and do, I don't need to say anything else but, "Thanks, I'm flattered, but I'm straight and married. Have a good one, man."
