You mean human fetus that grows and develops into human infant then human toddler then human teenโฆ.. but always a human person with inalienable rights.
When governments get to decide which humans are persons then you get the Nazis. Donโt be a Nazi.
Itโs a fetus. Itโs not a person. It has no rights. I would grant that once it can survive as a person outside of the womb then it should have rights.
