@Sean Johnson Well very easily, my point that he's ostensibly wrong for consecrated several bishops without even attempting to go through the proper canonical structures and is now excommunicated. Even Archbishop Lefebvre prior to consecration followed canonical norms, showing he was in no way rejecting the Pope or Schismatic. Initially they approved his request but due to political machinations by modernists they convinced Pope JP2 to delay the final approval. The modernist delay tactic in which they were hoping with Lefebvre's advanced age he would expire. I've heard Williamsons arguments for down playing the Holocaust but he himself never did the investigation, never provides any primary sources that show his numbers are correct. He only relies on discredited historians books who have been show in English court of law to be antisemetic and in making false claims.

@Sean Johnson Again that was initiated by Williamson who was wrong in the Rangel de Campos case, and unfortunately +Tissier followed him in this ordination. +Rangel was not SSPX and afterwards he wrote a letter to Pope JP2 promising fealty and loyalty to the Pope, in which JP2 then officially recognized him. Again Williamson taking along +Tissier in going rogue left Bishop Fellay at the time in a difficult position in which he couldn't really go against it after it was done b/c he would be seen as not supporting tradition, moreover, it became mute since JP2 recognized +Rangel. The SSPX should have gotten rid of Williamson -a loose cannon in 1991, instead of allowing him in later years to stay on and sabotage the full canonical recognition of the Society with Rome.
