There is a second factor involved, that has reduced the crime rate. However, Abortion Opponents should not leap to claim that that second factor is actually the only factor, because one thing the abortion/crime-link study found, was the early period by the 5 states that legalized abortion before Roe vs Wade. Not to mention that that second factor only focuses on violent crimes, and not stuff like, say, shoplifting, that someone might do to feed excess mouths.
I see JayDubya wasted no time spouting the usual Stupid Lie, equating unborn human animals with human persons, in denial of the Scientific Facts.
And Henrin somehow fails to realize that laws against abortion tend to
reduce the abortion rate, without actually stopping all abortions from being done. And so, after Roe vs Wade, far more abortions were done than before it.
Next, JayDubya reveals Great Hypocrisy, by stupidly opposing death before birth, and promoting death after birth. Because wanting to ban food stamps and other assistance has the net effect of an increased death rate among actual human persons. How is that in any way "promoting a human right to life", the primary argument JayDubya uses to oppose abortion? Meanwhile, of course, abortion only kills human
animals, not human persons, despite all of JayDubya's lying claims to the contrary.
Next, Henrin makes a mistake in saying, "The problem of young girls having children is with us regardless of what we do here towards abortion." That's because the actual problem is "girls having unwanted pregnancies", and this problem is
very relevant to Decisions made regarding abortion. Obviously, if unwanted unborn human animals are aborted, they cannot become children (who qualify as persons).
I will agree, however, with the first part of what Henrin wrote: "As long as food stamps and the rest exists these individuals will use it." Such policies essentially create an "ecological niche", the definition of which is, basically, "any environment in which organisms can survive and successfully reproduce". The
actual solution to the social problem is to somehow assist needy persons in their survival, while preventing them from succeeding at reproduction, so long as they are being socially assisted. (Good luck with the details of that, however!)
It should be noted that sometimes there is no such thing as a "deadbeat dad", simply because, sometimes, the dad dies before a pregnancy leads to birth. A "one size fits all" policy is always stupid.
Henrin reiterates the Heinous Lie of calling unborn humans "children", instead of "children under construction, with Murphy's Law a relevant factor in the outcome". It is well-known that a lie can consist of a partial truth. This particular partial-truth lie is Heinous because it encourages extra suffering when Perfectly Natural Miscarriages happen. Shame on you!
The next mistake Henrin makes is in this: "Like it has always been the majority of the poor would not become criminals, but be law abiding citizens like everyone else." While it is certainly true that the majority of the poor are law-abiding, it
also is true that the majority of criminals come from impoverished backgrounds. Therefore, logically, reducing the number of people growing up in poverty will reduce the crime rate, just as the study in the Original Post shows.
Next, JayDubya repeats Great Hypocrisy, by claiming (paraphrased) "there are situations in which Rome deserves to burn". Again this shows that JayDubya doesn't actually care so much about the lives of human persons, despite frequent claims to the contrary.
