UPDATE: Then, there's this, from Mark Steyn:
In practice, a culture that thinks Terri Schiavo's life...has no value winds up ascribing no value to life in general. Hence, the shrivelled fertility rates in Europe and in blue-state America: John Kerry won the 16 states with the lowest birth rates; George W Bush took 25 of the 26 states with the highest.
The 19th-century Shaker communities were forbidden from breeding and could increase their number only by conversion. The Euro-Canadian-Democratic Party welfare secularists seem to have chosen the same predicament voluntarily, and are likely to meet the same fate. The martyrdom culture of radical Islam is a literal dead end. But so is the slyer death culture of post-Christian radical narcissism. This is the political issue that will determine all the others: it's the demography, stupid.
