Government has a positive duty to protect life, yes or no?
I don't think anybody has argued that government should ever have the power to dictate who can and can't have children. At the state and local levels, it should have the power to ensure that any children produced are properly cared for and that can include removing a child from a home in cases of abuse, neglect, or inability to care for the child and placing the child in a safe environment. If we go with strict interpretation of original intent, the federal government is not constitutionally authorized to get involved in such matters.
So ultimately it all comes down to whether the unborn chld is consideredto be a life subject to the right to life, liberty, and the pursuit of happiness. Or whether it is a throwaway at the whim or decision of the mother. It is an even stickier wicket in states in which a murder of a pregnant woman counts as a double murder.
The pro abortion group desperately wants the unborn child to be nothing more than a mass of cells and to be entirely considered a throwaway if that is what the woman wants to do. Many think that if any part of the child is yet inside the birth canal, the child should be killed with impunity or an aborted baby that continues to live after the procedure should be killed or allowed to die. These are serious ethical issues for a whole lot of us.
And until those ethics are fully resolved, this will continue to be a volatiile and emotional issue.
