I really don't know where to approach your latest arguement, other than

, so I might just add the interesting theory that was first put forward in Freakonomics.
The idea is that in the early '90s, there was a significant decrease in inner-city crime. This has been attributed to economics, police action, etc, etc, etc. However, most analysts are still mystified, because those factors should not have affected things as much as was being demonstrated. However, the time of this sudden drop in crime was pretty much 20 years after Roe v. Wade and the building of affordable, available clinics where one could have an abortion in the '70s. The idea is that the unwanted children who would have been born in the inner cities would have become criminals, and since they were aborted, crime dropped on a huge level.
This is supported by the areas in which abortion clinics were adopted earlier and later, their crime drop was respectively earlier and later, depending on the proliferation and availability of abortion.
Of course, there is no way to prove this completely, but so far there haven't really been anyone that's come forward to disprove this in a major way. It's an interesting theory, for sure, and likely to be debunked if false, imho, because of its pro-abortion stance and the popularity of that book.
