As of right now, the SSPX has purged almost 1/2 of its professors, replacing them with priests ordained after its own internal "Vatican 2".
Fr. Le Roux is no Bishop Williamson; that's for sure. He's a "yes man" for Bishop Fellay.
Of the remaining 7 professors, 3 of them are brand-new priests. It actually used to be 4 (Fr. Asher is no longer on the staff)
