How many crack babies must a pro-life Christian adopt in order for pro-abortion advocates to think they....?

Pro-lifers aren't just Christians. I'm an atheist. It baffles me that people think that someone willing to have sex shouldn't also have the responsibility to at least give birth to that baby. If it's then unwanted it's considered a child, it can go to an orphanage if nothing else, at least then they have a chance to live.
