I think FV/NPP/AAT (I wonder how many names there will be to describe it in a few more years) is the main thing. Robbins, along with many many others, is unhappy that the PCA dragged it's feet for so long while this heresy got a strong foothold in the denomination. The courts of the denomination can be agonizingly slow sometimes. When the PCA finally did address this issue in a denomination-wide way, they bypassed the "normal" procedure - otherwise it would have taken even longer and in that time perhaps many others might have been carried off to FV's version of Rome.
