Some people choose to be married before God. Some choose to make promises to each other, irrespective of God. So far we're OK.
For some, marriage before God means the bonding of a man and a woman and as Paul didnt quite put it, its an institution to stop you shagging about. As it was put elsewhere its for men to practice being responsible, to love their wives as Christ loves the Church and presumably for the women to practice respect for their mate's decisions. Either side of the match could involve being patient and long suffering. Lets not go there, but its a lesson in negotiation and understanding.
Why are gay people being denied the right, not to marry according to one religious interpretation, but the secular one, to promise a faithful pair bond for life and to do so in front of witnesses? Why should a couple, together for life as a single unit find that the law gives them no rights over, for example, arranging the funeral if one was to pass?
Gay people are asking to be responsible. They are asking to be 'booked', seen by society as a pair bond.
To all you righteous, married, deep South anti-gay-marriage bloggers : How would you feel if you woke up one wet Tuesday; same life, same bed, same problems, different bits between your legs?
Still you, still as much in love with your partner as ever, as deep in understanding of each other, but short of a bit of tackle? Would you start shagging 'your own sex' (or your own sex as of yesterday) because society say you should? No! How could you? You would feel so sick at the thought.
This isnt about sex, who does it, how etc, its about love. If you woke up in the wrong body, there is no way in hell you could stop wanting the support, hugs and affection of your marriage partner, wanting to work with that person as a unit in society, two become one soul, never mind body. But it would technically be a gay marriage.
Have a heart.
