It's your argument. I didn't say it was a convincing one.
You tried to make a distinction between homosexual behavior and other behavior which are clearly outside the boundaries of societal mores of our day. You said that other behaviors that are illegal are illegal because society has an interest in regulating them. I then pointed out an interest society has in regulating homosexual behavior and you shot down your own argument. So are you admitting there's no distinction between the behaviors which you said society could regulate and homosexual behavior?
