Well as you say and you correct, sex outside of marriage between two straight people has no effect on marriage between straight people.<quoted text>
Why do you think "get sex" = "gay marriage"?
If a man and a woman (that's not married) have sex, does that have ANYTHING to do with straight marriage?!
Not so with gay marriage. Sex between same sex for thousands of years has always been the taboo and the barrier to same sex couples getting married.
No matter if the gay couple marry and not having sex, that don't matter. What matters is the greatest barrier to same sex marriage has always been same sex sexual practices. Thus those practices especially in the light of the Supreme Court entry into the argument, those practices should be discussed and analyzed to the maximum in the public arena. And that what I doing.
Who like it or not like it, is not my concern.
