I will continue to fight to make sure that the cultural elites don't further undermine the institution [of marriage] that gives the best opportunity for healthy, happy children and a just and prosperous society.
You can't fight cultural elites with political weapons. Film makers, journalists, artists, university professors--these people care little for what a conservative politician says.
Even if you legislate a law against their positions, it will be overturned in a generation (or less) since these elites are the ones who train our youth and future political, cultural and business leaders.
This is why liberalism, despite being a minority position, holds ascendency in our world. Power lies in cultural transformation, and conservatives own little of it.
There's a sense in which we lost the cultural battle generations ago, when the fundamentalists fled the universities and similar cultural institutions and let the secular perspective reign unchecked.
We are just seeing the fruits of that capitulation.
There's hope, but the change will be generational, and will involve sending more Evangelicals to the university. This is also reason to be glad many Evangelical philosophers have made headway into the university setting. There is a very real sense in which philosophy undergirds all cultural pursuits.
It will also entail giving more money to foundations, scholarships, etc., for Christian artists, lawyers, academics, and similar groups--another reason to support sending more Christians into business, since they are the cash cows for serious, lasting cultural efforts.
