I don't think they want to support fetuses (through prenatal care) either. I think it's just about protecting the "life". Pro-life people don't see a difference between killing a 3 month old baby and destroying a fetus at 3 months.

Anyway, I think that's mostly irrelevant. Say conservatives decided that abortion would be banned nationwide but there would be comprehensive social programs to care for pregnant women and children. The banning of abortion would still be a terrible idea.
