FWIW, the Catholic Church has the most expansive view of pro life. It is essentially humanism taken to its logical conclussion. The differences we draw between ourselves are meaningless, every person, regardless of stage of development or current human condition, has an inalienable right to life.
For the record, humanism is not the idea that every human has an inalienable right to life.
Humanism is the idea that people have an inalienable right to live their own lives.
Quite a difference between the two.
