I think gay pride celebrations should be whatever they want to be.
Let your freak flag fly, let it all hang out, be yourself.
It's definitely not a time to stifle the fun and stuff it down like the conservative community would like us to do.
It's one time when people in the closet see other people doing whatever they want to do and being who they want to be. And maybe that will give them the courage to be themselves and come out.
