As in anything, there will always be outliers. You can't make the outliers the foundation of your argument. Anyone who doesn't want to be pregnant is not going to voluntarily remain pregnant if they have a choice. The morning after pill is by far the most sane solution. It should be available for free in massive quantities. Assuming that you can affect the sexual behavior of people through religious creed today is a waste of time in terms of public policy. It didn't even work that well in the past but did result in an awful lot of orphanages. Like it or not, unwanted pregnancies are not going to stop happening.
