my overall point was that we as people exercise our first Right by being born
keeping someone from being born is to deny them their basic Rights, by definition
Philosophically speaking, the Preamble of the Constitution sets an even higher bar.
The Preamble explains the entire raison d'être and specifically includes, among its purposes to, "...secure the blessings of liberty to ourselves and our posterity..."
If one defines 'posterity' as those generations to come, or those yet unborn, it would appear the Constitution's declared intent was to recognize and protect the rights of Americans not yet conceived, much less those unborn :-) To deny that, one would have to come up with a pretty twisted and tortured definition of "posterity.'
The right to Life is listed as one of those “inalienable” rights endowed on us by our Creator. So you are absolutely right.
