Yet gay marriage not only will have consequences, it already is visibly having them. "Marriage equality" as an idea means viewing traditional understanding of marriage as morally wicked and illegitimate -- "discriminatory" and "bigoted" and "hateful" in the lexicon of sexual liberalism.
Sexual liberalism is a new public morality that tries to reform society based on two great lies about human nature: Men and women are just the same; and sex has nothing necessarily to do with babies.
At the heart of sexual liberalism is severing the ties between sex and procreation, which requires culturally shoving the reality of procreation under a big, wet mental blanket. Sexual liberalism requires a new set of sexual taboos to blind our minds and divert our attention from great and obvious and important human realities, first in the name of gender equality and now orientation equality.
The most important thing about sex is that it makes new life and either connects or disconnect babies to their mother and their father. A culture that no longer actively and energetically strives with great vigor to connect sex, love, babies, and mothers and fathers, sees these things fragment at great human cost.
The word for how we connect them is "marriage."
That the majority of the American people continue to vote for marriage is a moving testimony to the power the truth exerts, relentlessly but not inevitably, over ideology. To willfully blind ourselves to these enduring sexual truths is a form of self-mutilation to which the human soul only uneasily accedes.
Combining the goods of liberalism (respect for pluralism, diversity, maximum opportunities and social respect across deep moral divides) with the great task of any human civilization in sustaining a marriage culture is hard and would require original and thoughtful moral and social work.
But it begins with the immense project of rejecting the lies on which sexual liberalism is based.
