IMHO abortion is one of the most vile practices & should only be allowed to be preformed in the most drastic of scenarios, such as either to save the life of the mother or in case of rape or incest.
In all other cases the mother willingly chose to spread her legs w/out the use of contraceptive measures & created a human life and that unborn child should be protected by society even if it's being protected from it's own murderous mother.
It's not a parasite, it's not a cancer, it's not just a clump of cells, it's a child.
If it's a child, then your position is morally inconsistent, unless you also think that the children born of rape and incest should also be subject to being killed.
