But cultures that have babies and pass their values onto those babies grow and prosper. Those who don't are replaced by those who do. The culture that has liberated women (an issue obviously dear to the author's heart) is, for the most part, white, Christian, American culture. If folks like the author continue to sneer at efforts to continue that culture, the author will find his granddaughters in burkhas.
The problem is precisely, that to the extent women's liberation results in falling birthrates, it is an entirely self-limiting ideology that can prosper for only short historical periods. The pity is it will drag a lot of other things down with it that will be very hard for mankind to invent again--such as the Rule of Law, private property and stuff like that.
