Which part of this do you not understand?
“No person shall be deprived of life without due process of law.”
“No State shall deprive any person of life without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.”
Under the Constitution, one is a citizen once they are either born or naturalized as a citizen.
Under the law of all 50 States (Oklahoma is currently attempting to change this) one is only a legal person once they are born.
Legally the unborn are not citizens, nor are they a “person” under the law of all 50 States.
You can think that is wrong - you can try to change that (Oklahoma is currently attempting to do so) - but it is obvious that you are absolutely ignorant concerning the law and the Constitution.
