"The failure of the theory you pose lies in the belief that marriage is and always has been nothing more than a religious rite. Long before Judeo/Christian practices appeared in society the so called institution of marriage existed. It is not some sort of exclusively religious rite but a civil contract."
Name one society ever that allowed and condoned homosexual marriage? Religious or not. What you want has never been accepted in human society. You are free to hope and work for that to change but as it is not at all natural, you will have a difficult time.
