By your apparent way of thinking, the definition of what's a baby and what's "a blob of fetal tissue" depends on either the child's physical location (in or out of the womb) or the mother's personal feelings at the time. That's ridiculous.
What you're calling for is government sanction of personal irresponsibility, and trying to mask that behind the flawed notion that state sponsored abortion is less of a financial burden on the taxpayer than the subsequent welfare will be. Whether you realize it or not, you're using a favorite tactic of the left: casting the issue as if it only effects the poor. It doesn't, and considering that the victim in all this - whether wanted or unwanted - is a baby, then greater emphasis should be placed on the ramifications of promoting such behavior.
This.
