People will tell you that you should never become an activist seeking to make abortion unacceptable or, heaven forbid, illegal. Instead, they say you should focus on underlying causes. Rape has underlying causes. Should we make it legal and instead try to treat its underlying causes? Come to think of it, spousal abuse has underlying causes, too. We would never elect a politician who ran on a platform of making it legal for a man to beat his spouse. But we routinely elect politicians who run on a platform of saying it should remain legal for a woman to kill her baby.
Pro-aborts never argue as if the unborn child is a real human being. Because the moment they do, they lose.
