I'm a strong believer in life and I'm very prolife. The only reason I can see to end a pregnancy is when it risks the mother's life. And no Doctor or government official can make that decision only the family can make such a decision.
Roe vs. Wade was decide on the matter of privacy (Doctor vs. Patient privacy). If a person was to attempt to or kill another, no right of privacy can protect the guilty! So Roe vs. Wade is decided on the wrong idea and principal.
The Fifth Amendment states: "No person shall be deprived of life, liberty, or property!"
The Fourteenth Amendment states: "nor shall any State deprive any person of life, liberty, or property, without due process of law;" So that makes murder of a person a crime and any law allowing it Unconstitutional!
Then the argument of when life starts:
I say that doesn't matter when life starts according to the Constitution. So lets find out why:
Let's take a look at the preamble to the Constitution:
We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defense, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.
"And secure the Blessing of Liberty to ourselves and our Posterity"
The definition of Posterity: posterity n. 1. Future generations. 2. All of a person's descendants.
If they used either term descendants or generations you could argue the idea of when life starts.
But the founders didn't use any of those terms they used Posterity, and doing so the argument of when life starts is mute and doesn't matter, since all generations including all future generations shall not be deprived of Life, Liberty or Property!
