But patriarchy always makes a comeback, because its adherents put more genes and ideas into the future than do their secular counterparts. This process is already well under way in the United States. For example, among American women just now passing beyond reproductive age, nearly 20% are childless and almost as many have only one child. Consequently, a relatively large share of the next generation is descended from a comparatively narrow and socially conservative segment of society that places a high value on reproduction. Today we see a culture in which social conservatives and the religious-minded play a far greater role than they did forty years ago. (Breakthrough Ideas for 2007)
It’s ironic that liberalism is in decline by it’s own venerated evolutionary mechanics.
