"Legal" marriage is a secular contract between two partners having NOTHING to do with religion. It therefore doesn't matter what your religious self thinks about gay marriage. Marriage sets out the rights and responsibilities of the partners to one another, and the manner in which joint assets will be split on the dissolution of the marriage, as well as spousal support in that event.
Furthermore, unless the State is forcing or requiring you to marry a same sex partner, same sex marriage isn't being "forced" on you or "shoved down your throat". The bald fact is that unless you're a gay person who wants to get married, the legalization of gay marriage will have absolutely no impact on your life at all. You're simply a miserable old man who keeps trying to inflict his idea of morality on other people.
I think it's wrong and immoral for people to choose to remain single and childless. God told people to be fruitful and multiply and you have ignored that command. You don't even replace yourself, and you use all kinds of resources in your final years, you've contributed nothing to create. I believe being single and childless is an affront to God's plan for us.
YOU should have been required to marry and raise a family. You have been socially irresponsible and gone against God's will and natural order of things.
If you found this argument to be stupid and an affront to your rights as a citizen, that is how I feel about your stance against gay marriage. Jesus spoke not one word against homosexuality, or "immorality". He preached love and acceptance.
So take you "religious ideals" and stuff them. They have no business in other people's lives other than your own.
