Because sluts rarely care about abortion all that much. It's more of a political precedent these days than the whore wanting to kill her kid for future comfort.
But it is a good point, why not let poor women, especially those being abused by their husband, or God forbid young girls being raped by their own family.
I'll tell you this, personally, if a rape victim would get an abortion, I would not dare hold it against them and I would not dare even to blame them, but I would dare to call abortion the killing of an innocent child any day to any one, though not as dedicated as leftoids like Triple H want to claim how insignificant it is.
So that's my main problem. You can figure out examples of where abortion seems profitable, but that just goes to show how far society can stoop down to that instead of trying to figure out poverty, help disenfranchised kids and orphans the claims gets to be that it's better to kill them before they realize how shit their lives COULD be, maybe.
Also on a funny note, there's this joke that I heard from an orphan who grew up to be a successful business man who said that he hears people say that poor women should get abortions, but he's glad that his mom didn't listen.
