But the two aren't necessarily mutually exclusive.
Look, if they're getting an abortion it's either a health issue or they believe they legit can't take care of the baby. If they can't take care of the baby, it's really not a good idea for someone (i.e. The state) to say "tough shit give it a terrible life because god says it starts at conception" when in truth it's just a clump of cells for a good period of time without consciousness. And you can't say preventing a life is the same as killing because if that's the case men commit genocide all the time just masterbating or pulling out or using a condom. Unless you're a practicing catholic, then I guess I gotta just say I respect your dedication.
I don't feel capable of making that call, because I do take that potential child's life seriously, but I don't think you're capable either, honestly the only people that have the full authority on the subject are the mother and the doctor with some input from the dad.
