You didn't answer my question, and the bolded ignores it. Many heterosexuals who marry CANNOT procreate, for a variety of reasons.
Would you restrict their marriages?
I did answer it. But when you're argument is based on lies, you ignore it and don't like it. It is not a question of whether one will procreate, but that they can.
You also refuse to acknowledge the historical purpose of the institution of marriage and answer my question; why do gays need a Government sanctioned piece of paper to prove their love?
