Here's another helpful piece by Bob Patterson. This one ran in The Daily Beast and here's a teaser:
...the United States has been anything but neutral on fertility, as public policy has chipped away at our formerly high birthrates for four decades. Indeed, today’s upside-down demography is the fruit of three heavy-handed policies that triggered immediate and permanent declines not only of birthrates but also of a key correlate of fecundity, marriage rates. The triple-witching spell was cast by Richard Nixon’s massive birth-control crusade through Title X of the Public Health Services Act and Title XIX (Medicaid); the Supreme Court’s Roe v. Wade decision, which sanctioned abortion-on-demand and trashed the hallowed custom of shotgun weddings; and the states’ imposition of no-fault divorce, which downgraded the marital bond to a precarious “at-will” relationship.
Note the comments by a bunch of bloodthirsty narcissists who think hissing and spitting are modes of argument.
