1.)Also to claim that homosexual activity is no different than heterosexual activity is not an absolute truth, either. If i am out and i see a husband and wife give each other a little kiss on the lips, i don't think twice. If i were to see two men do the same thing, it will bother me. I don't care if they're married or not. 2.) I simply find it distasteful, at best, to view such a sight. That's not me, or anyone else, 'pretending'. That is a genuine dislike for that behavior between two men or two women.
So the issue doesn't even need to extend into sexual behavior, as casual, affectionate behavior common among dating or married couples is still enough to affect people. And i feel certain God is going to be bothered when two men kiss or perform other acts of affection done under the banner of homosexuality. 3.) I don't see God being bothered by those same acts being performed by a man and woman.
