Paul Gottfried, History, the Holocaust, and the Doctrines of the Church

Professor Gottfried takes on the lefties. Unfortunately, he gets the reason for the excommunications wrong:

Church authorities, however, are authorized to excommunicate those who reject church discipline or who openly deny some basic doctrine. Still and all, in the past century or so, the Vatican has not been kicking out confessing Catholics very often. What happened to Lefebvre and his followers was not a common occurrence. It was directed against those ultra-traditionalists who resisted the changes introduced by Vatican Two. Lefebvre and his followers repudiated the Church’s teachings, as proclaimed through Vatican Two, about the uses of vernacular liturgy and about certain alterations in the priest’s role in the Eucharist.
