“Murder, Rape, and Theft are all Laws which are defined and enforced at the State Level. If you believe Abortion is Murder (and I do) — then, Constitutionally, that area of Law is handled by the States.”
So you believe that individuals should have different rights depending upon the state in which they happen to be? That’s exactly what you’re saying here, that an unborn child should have the right to life in one state but not in another?
Constitutionally speaking, Murder Law, Rape Law, Theft Law, etc., are all defined and enforced by the States. If you want the Federal Congress to define and enforce National laws against Murder, Rape, Theft, and what have you, then you need to write up Constitutional Amendments proposing that the Congress by granted jurisdiction over all those areas of Law -- and then get such Amendments passed by 2/3 of the Congress and 3/4 of the States.
Because the system established by the Founders places those areas of Law -- Murder Law, Rape Law, Theft Law, and most other crimes against persons or properties -- under the jurisdiction of the States.
