I am not sure I get what you are saying here.

However, the person-hood of the fetus is a very important question.  If the fetus is a person, the fetus is subject to the same constitutional projections and rights as any legal US citizen is.  Even if the fetus does not enjoy the protections of the US Constitution, the right to life is inalienable. That right does not come from the government.  

The point is that no person can be murdered under the guise of  "choice." The reason fetuses can be murdered is because they are not recognized as persons.
