Abortion is simply a matter of whether or not you believe there is a human being who is being murdered.
For those of us who believe the child in the womb is as important a human being as anyone else, there simply is no argument persuasive enough to convince us it should be legal to murder that child.
Affordability of a child? Affordability is an issue at every age. Being able to afford children can arise at any point. Layoffs, divorce, death of one of the parents, etc. So the affordability excuse for murdering a child is specious.
