The Constitution is absolutely concerned with life. You made some excellent points that we are indeed talking about a life. If a life then that life should be protected by our constitution. The line was already crossed when the Constitution was used to deny this life it’s inalienable rights. A law recognizing that life as life, does no disservice to the several states nor the constitution.
It most certainly is.
The Constitution's purpose, according 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.
