It's a good business decision that has nothing to do with gay men and PCness. Do you think gay men want to sit around a club with a bunch of screaming, outta control women? The reason a lot of clubs allow men now is because there are only so many women who go out in girl-only hordes on the weekend. You attract more business and pack em in more, when you allow women to bring dates, boyfriends, brothers, whatever. The clubs for women that allow men, usually require the men to be accompanied by at least one woman.
