In 1960 there was no Roe v Wade decision, nor an imminent social security crisis due to falling numbers of populaces to support the "Great Society".
If the Catholic Church takes a different path, a more liberal path, you can expect an expansion of an "Ingrate Society" that will eventually devour itself, just what so many lefties and anarchists have been trying to facilitate for so long.
Personally, I agree with some FReepers who've suggested that Terri Shiavo is the RATS' solution to Social Security. If they're disabled and inconvenient, get rid of them. "Logan's Run" isn't far off if they succeed.
The number of abortions went from about 250,000 to more than 1,000,000 in the year after Roe. If those babies, or the majority of them had been allowed to live and grow up, there would be no call for Mexican immigration.
