I beg to differ.
Forgive me for the brevity of this message. I could potentially write pages on this one.
The most common argument for legalizing same-sex marriage is indeed the fact that two people regardless of gender and sexual orientation/preference should be allowed to marry each other as much as the “traditional” couple next door. The reason why they are not allowed can be explained in more ways than one. Unfortunately, I do not believe your argument is remotely one. The closest justification you may be looking for is the fact that our politicians are so obsessed with winning elections that they can’t give up the idea that church and state are separate, and they always have been. We do not go by “heavenly” values, we have never done so! We are the wealthiest and most powerful nation because we know how to squash and silence those who don’t serve our interests (U.S. Corollary is a good start should you wish to explore). And we do not do it in the name of anyone but us!
I do not agree that the government’s motivation to not support or legalize gay marriage is because it believes in the superiority of marriages between opposite sex as opposed to same sex. Given the rate of divorce and children born off wedlock, it would be comical to believe that children born from tumultuous environment are better off just because their parents are opposite sex (or straight). What shapes a human being may begin in the household. However, that is only part of the effort. Remember, “It takes a village” to raise a child. It is the schools, the elders, relatives, friends and the environment that shapes a child. Lack there of is part of the cause for many of our social issues in America (obviously this is true for the rest of the world as well). If the government knows anything, it should know this. The most recent US census reports on divorce are a testimony to that. There were half as much divorces for all the marriages that took place in 2009 (it doesn't mean there were 50% divorce rate due to other facts I'm not interested delving into). Gay couples or any couple is as much capable as anyone else in raising responsible and exemplary citizens that will serve the country well for generations to come. The only requirement is that one be equipped with the courage and know how that is necessary in raising an offspring.
Please understand that there are exemplary citizens that were born from a broken home. Our very President is an example. A mother, a stepfather and maternal grand parents raised him. Sure none were gay (as far as we know). I can list examples of the opposite scenario on and on. All I need to do is check any criminal’s prison records, and we got plenty of them right here in Texas. I am very certain that many came from wonderful, loving, straight parents. I do not even want to venture to good or bad parents who raised a homosexual with a success story. Does it mean the government does not want those? How about those who defended their country and did so with honor and dignity? Should we deny them equal rights because they may not raise as good a citizen as the government requires it?
So should the government punish married, straight couples whose child committed a crime because they did not “raise him or her right”? And reward those who “did”? Your message does seem to have ignored practically all avenues of measure to a conclusion that is nothing short of alarming.
The government is (or should be) in the business of providing the infrastructure and necessary tools to help us raise exemplary citizens of the future. That is why we pay taxes for. The government is NOT in the business of determining which kind of parents or people raise better people. It is not in the business of profiling based on gender or looks or race. Like many of my peers, I would like to believe America has moved on. So should those who came up with this sad, meaningless and one-dimensional theory.
