If you believe the proponents of Prop 8, then the reason the state sanctions marriage is for procreation. If this was the case, I should have never been allowed to marry since neither of us wanted to have children and took measures to ensure we didn't. By the same token, no one over 55 should be allowed to marry. No one who is infertile should be allowed to marry. Indeed, the primary requirement for a marriage license should be a pregnancy. Yet these same people only want pregnancy within marriage.
To say their arguments lack logic and merit is to give them far too much credit. The same people who do not want committed gay and lesbian couples to marry because it would sully the sanctity of marriage have no problem with multiply divorced hetero couples marrying. Why aren't they opposed to divorce? The fact the most marriages end in divorce is far more a stain on marriage than allowing same sex couples who love each other to enter into it.
I guess when you have the word from on high, you can ignore the failings of your argumentation. But wait: What is traditional marriage? In the Bible, all of the patriarchs had multiple wives and concubines. If you're looking for true Biblical marriage, there it is.
And Jesus does not offer a better picture of marriage. In Luke 14:26 he says: "If anyone comes to me and does not hate his father and mother, his wife and children, his brothers and sisters—yes, even his own life—he cannot be my disciple." Or Matthew 19:29 "And everyone who has left houses or brothers or sisters or father or mother or children or fields for my sake will receive a hundred times as much and will inherit eternal life." Hardly what one would call a ringing endorsement of "Biblical marriage."
I am friends with a lesbian couple who have been together nearly thirty years and a gay couple who have been together nearly fifty. If marriage is about love, then they deserve to be married. It it's not about love, then what is it about? Certainly not what the Prop 8 proponents say. We can only hope the Supreme Court shows courage and forethought in their decisions.
