Abortion has always been a choice, whether or not it's a legal one. People who feel the need to get an abortion will find a way to get one. The question is, will it be safe? Making abortion illegal doesn't prevent abortion, it just causes unnecessary injury and death. We can and should have a debate about our public health approach to unintended and unwanted pregnancy. But abortion has to remain legal, for the same reason that drinking alcohol does -- prohibition is more harmful than legalization.
