First of all, I was making a little joke and wasn't intending to offend anyone.
That said, if it's a stereotype, it has (like most stereotypes) a certain basis in truth -- most theatre fans ARE female and/or gay.
According to a survey from the League of American Theatres and Producers, nearly two-thirds of Broadway theatregoers (64%) are female. While the same survey does not provide a break down by sexual orientation, I don't think it's a huge stretch to assume that a fairly large portion of the remaining 36% of theatregoers who are male, are also gay (a fourth? a third? half? Who knows....).
That a relatively small percentage of theatregoers (and presumably posters on a theatre board) are straight men -- not that there's anything wrong with that, to quote Seinfeld -- is hardly a surprise. No need to be defensive. That your sexuality deviates from the norm here certainly won't be held against you by anyone -- we're liberal that way.
