"Religious degrees" are academic degrees (or in some cases professional). A theology PhD in most cases has a lot more education (credits and years) than standard PhD tracks. No one should advocate allowing substandard degrees to be issued unless they meet normative standards for that field. The argument that because a school calls itself religious, it can issue substandard degree titles is ridiculous. The state may not interfere theologically but surely it has a right to set standards for degrees as it does for drivers licenses or any other number of regulated activities.
