Thanks for your responses, guys and doll. I know it's kind of a complex question and there's probably no definitive answer.

Abraxas, you made perfect sense to me (of course, I'm kind of used to not firing on all cylinders myself). I agree with the four "differents" - it can mean various things to various people, and there is no one answer.

Poccy, I liked your comparison of gay people to trans people. You're right that it certainly doesn't define all, but for some people it does. And I'm sure that receiving an invitation like that would have upset me too.

Kerri, I totally get where you're coming from and thanks for sharing your experiences and point of view. I think, however, that the invitation shouldn't have been exclusive, but instead should have stated that anyone who starts trouble (male, female, trans, cis, gay, hetero, etc.) would be removed from the premises or dealt with in some way.

I guess I just don't like generalizations and things that cause rifts among groups. Something like this can cause more divisions than what we already have in society - it can make genetic men who are caring and supportive (and we know they exist) decide that they're considered "the enemy" and that their friendships and support are not wanted. And it can cause those that have not yet made up their minds about us become less understanding and more close-minded. It's kind of sad, really.
