So? Fleas are parasites, certain species of plant are parasites, viruses are parasites. Yet no-one would deny that a flea is always a flea, a strangler fig always a strangler fig or a cold virus always a cold virus - from the very first second they come into being.I think the ability to mate and produce young could be a boundary marker of species.
A pro-abortion argument is that the ‘tissue’ is a parasite and not yet a human.
