The more we take the risk and put ourselves out there - the more we will be accepted. I remember back in the days of Harvey Milk - when he started the whole come out and be seen revolution. Every SF Gay Pride was filled with speakers encouraging everyone to get out into the world adn be seen and to tell everyone you know that your gay/lesbian. I think it was a profound movement which began our path to true equal rights.
I've been to two straight weddings in the past year or so, in Ohio, and there were young lesbian couples dancing (slow too) with each other and no one gave them a hard time - and didn't really even seem to notice.
