In my mid-twenties, I learned that taking your female friends to a gay bar is like taking a vegetarian to a butcher shop. There is a lot of meat, a lot of prime cuts, and even a little tripe, but nothing they can eat.
It's a dirty secret of a subculture of the gay male world about women: That they're essentially unwelcome, unless they come to us as a Real Housewife, a pop diva, or an Tony award winner–or an unassuming fag hag. To anyone just coming out of the closet and hoping to get his bearings in the gay male community, the attitude towards women is simple: They are just objects whose function is to serve gay men. Maybe it happens when gay men get too comfortable in newly-discovered safe spaces–where they get to call the shots as their proudly out new selves. Or maybe it happens through cultural conditioning. Whatever the cause is, it becomes clear: If there isn't any kind of transactional exchange happening, then women lose their value in gay male subcultures.
