Vast human experience confirms that marriage is the original and most important institution for sustaining the health, education, and welfare of all persons in a society.
No doubt many gay Americans would agree. Which is why, perhaps, they would say they are entitled to the same recognition and governmentally conferred benefits as married heterosexuals. Indeed, they say that it is a question of civil rights. And if you don't agree, you're just a homophobe.
But what's really at the heart of the homosexual civil rights argument with respect to the specific question of government-sanctioned gay marriage? The answer has been completely shrouded by the misdirection outlined above, and it has nothing to do with hatred or bigotry. Rather, it has everything to do with science and, ironically, children.
While many progressive gays -- and the left in general -- happily use science, especially Darwinian evolution, to denigrate God and religion, they ignore the many correlate scientific implications of evolution's fundamental mechanism: natural selection. For those with even a cursory knowledge of the science, the obvious truth is that homosexuality has, in evolutionary terms, a negative survival value for the species -- since homosexuals are less likely to reproduce -- and is by definition a dysfunction.
Naturally occurring? Yes, certainly. Normal? No.
Make no mistake: this is not some highly speculative theoretical construct, such as modern physics' String Theory; it doesn't require quantum-mechanical mathematics. It is more on the order of an axiom, which is to say that it is self-evident.
Unfortunately, the "political correctness" cudgel more or less guarantees that most working scientists whose specialty is evolutionary biology would be hard-pressed to admit this -- because virtually all American scientists are the product of U.S. colleges and universities, where huge majorities of the faculty are self-described liberals for whom political correctness is an article of faith. These scientists, many of whom still work at those colleges and universities, would never allow themselves to put at risk their job, their grants, and their prospects for tenure.
Perhaps most importantly, the recognition of the nature of homosexuality clearly and definitively refutes former Solicitor General Ted Olson's main argument in the California Prop 8 case, horribly and misguidedly decided by Judge Vaughn Walker, that gay marriage is a declared right because of the Supreme Court's decision in Loving v. Virginia, which struck down the ban on interracial marriage. However, Olson, perhaps unintentionally, is making a wild conflation between race and affective impulse with evolutionary consequences. In other words, race is not a dysfunction, and gays come in every racial variety anyway.
