Imagine how much of an uproar there would be if the church started saying that they didn't want black priests. I don't see why this is any different.

OK, I'm not saying I'm gay (because I'm not), and personally I don't think it is natural (imagine if everyone was gay...no more babies being born)...but, if people wish to be gay, then let them. I wouldn't want people banning me from things because of something as trivial as sexual preference, or anything else.
