It definitive seems like a connection between a lack of social support and an emotion reaction to penalizing people for getting pregnant. On the extreme end we have a culture where the man should take responsibility for getting the woman pregnant and where abortion is seen as a way for both to escape responsibility. Support comes from the family rather than society, which also means members of the family is responsible towards the family. The closer people holds to those values, the easier society accept laws like anti-abortion. Religion do play a supporting role in this by holding onto the values, but is itself not always in the center.
