I agree. The world is not as open as it should be. That's all the more reason for me to be open, normal and casual about being gay. It's a non threatening way of showing that we're there, not hiding neither very exposing.
I think that's the way of opening up the world around us, by making them say: hey, those queers are after all not that queer....
For the record, I am straight (and I am only saying this coz so many people seemed to think I was a transexual!) but to me, a person's sexual orientation is of no consequence whatsoever, unless, of course, I am trying to shag them.
Decent people don't give a s**t, and who cares what the non-decent people think?
