"in exercise of her natural right of self-determination "
Can a man claim self-determination and refuse to pay child support?
If that were the rule, there'd be a lot more abortions. Remember, in most cases a woman chooses to abort because of her own desperate circumstance. Folks here love to label such women as murderers, but the reality is that many believe they have no choice. Especially when the unexpected byproduct of a consensual relationship spurs the man to walk out the door and abandon his responsibilities. Left on her own, with no partner and afraid of the reaction of her family, the woman feels she has no choice but to end the pregnancy.
It is situations like this where the pro-life movement is most effective. Not when it demands the State coerce its moral perspective. But when it provides real support to women in desperate circumstances, so they understand and believe there are better options than destroying the nascent life in her womb.
