Lots of good reading here. Thanks guys.
I suppose I should clarify what I meant by "gay culture" - it is everything in the gay community that revolves around the pursuit of sex. It includes all the fashions, boutiques, attitudes, sexual cliques, bars, clubs, gyms, tanning salons, day spas, dance clubs, and gay newspapers and magazines all which feel off each other. Surprisingly it isn't very different from city to city or from country to country for that matter.
It is a culture based solely on sex and the pursuit of sex. So naturally it creates and perpetuates its own value system based on superficial things like looks, age, race, dick size...etc. It tends to exclude straight people and divides gay men into meat types, twinkmeat, bearmeat, musclemeat, blackmeat, asianmeat, leathermeat..etc. So it is not at all inclusive or generous. It is a culture that's held together by sexual attraction. Ironically that glue that holds us together is the same glue that keeps us apart.
