My point, and I do have one, is that I agree that a certain level of decorum is necessary, but I find expressions of simple affection by any gender pairing is sweet. Just reminds me that love is a good thing. It really isn't about parts, but about hearts. Gawd, I sound like a Hallmark card here.
As a society we are unaccustomed to seeing same sex couples express affection. I think it's just a matter of giving us all time to adjust. At this point the gays all cheer any broadcasted kissing and the straights mostly get edgy. Everybody needs to settle down if same sex marriage is ever going to be just another part of our society.
