"When the fetus can live outside the mother's womb, then its afforded human rights."
Given medical advancements a fetus is now possibly viable at 22 weeks. Is that the point you would grant human rights? That seems a completely arbitrary distinction to me as medical advancements have gradually advanced, and may advance further, reducing the term to 15 weeks, or 10 weeks, or possibly less.
Regardless, human action is required to halt the pregnancy and end the life. If no action is taken to end the life, the life continues.
Infants must be cared for years. Deny care to a child and the child will surely perish. I expect nearly all people would object to denial of care for infants.
The only bright line I can see to determine when life begins is conception that without human intervention the life results in a living human being.
Do you think men should be required by the government(acting on behalf of society) to provide support for the children if they father a child?
I am entirely unfamiliar with the Santorum story. As time allows I will look into it.
I am however unaware of any government subsidies that are available to home schoolers, but I could be wrong. I would likely be in favor of a voucher for all students. Those vouchers would travel with the student to the school of their choice. I think eventually that would result in far fewer government run schools and much greater educational achievement and success, and much lower costs.
On an different subject, are you opposed or in favor of capital punishment?
