Gee, dating someone of the same sex doesn't make sense to me. But you know what, if that's what you want, fine. If the party facility doesn't want to host your party, fine too. It's called freedom - no one can tell you what to do, and no one can tell the party place what they have to do either.
I see this as another form of bullying. NBC and the gay couple are bullying this small business because they don’t believe as the gays want them to believe.
