A very astute observation you have there my friend.
While there may be many reasons for this divide, personally i feel that the whole 'stereotype' thing may have antagonized the masculine gay population. Because of the effeminate gays, homosexuality has been 'branded' as being that of fem guys. So many times i've seen in my community that people see a fem guy and say---Oh! He's soooo gay!!. while masculine gays, when found out that they're gay, are referred to as straight acting gays or something like that.
Again, as Graeme put it...it's a personal thing. And he gave a very good reply to your concern. I had the same thing in mind.
Not many homosexuals have this divide.. It's just a subconscious thing...just like the cold war between males and females...
Just my two cents.
