My point is that, by removing downsides to having kids out of wedlock (ie, the girl could get the guy to pay child support with or without marriage), it directly and predictably led to a large increase in out-of-wedlock births.
That may be true, but the alternatives are abortion (which punishes the child) or children living in poverty (which punishes the child).
No matter which way you look at it, when one or both parents abdicate responsibility, children pay the price. They always have
Abortion is a just a more modern, convenient way to get the same result ... get out of responsibility. Because it is so convenient more children pay the price with this method.
The very LEAST we can do is not contribute to the problem by condoning the shifting around of responsibility.
It is extremely clear who is responsible for a child coming into existence and for its welfare: the two people who created him/her. We should insist that these facts be stated clearly and without any equivocation whatsoever.
