It's about hypocrisy and ignorance. They want to control the bodies of women. They're the party of small government, but they don't wish to pay for abortion because? They'll end up paying for the mother and baby's health care, schooling, and food. Government's pay for all the social services for more people. Some young girls should not be responsible for another human when they are still children themselves.
Their philosophy of small government has no meaning. They still want to control other people's lives.
