People who are completely dependent upon another do not have any Rights. A Right is defined as an action or behavior that does not require the permission of another to act or behave. Privileges require permission.
Dependency requires permission to anothers' property. A person can withhold permission to their property/self at any time otherwise we have no Right to our person.
A fetus is 100% dependent therefor has no Right to Life. It can only be said to be Privileged. How privileged? Look at the parents.
Independence is the ONLY path to Rights.
No Liberty No Peace, Know Liberty Know Peace!
