Let's say someone enters your house, or you let someone in, and that person ends up posing a danger. You own a gun. The State does not have the right to tell you what to do--you have the right to determine, in your own house, how you will deal with the dangerous person. You also have the right to determine what is and is not a danger for you. If you kill the intruder, even if you invited him in, and you believe you were in danger when you killed him, no one can prosecute you.

There are some situations where the state can intervene, and some where it can't. God trusts women to make decisions about their pregnancy without intervention from the State.
