"It is undeniably true the facts about the man you follow are radically different from the mythology about him you promote"
The mythology is the nonsense you spew. The truth about Archbishop Lefebvre is very little spoken of these days--that he was missionary priest living in poverty in Africa for most of his adult life, that he above all had been responsible for the burgeoning of Catholicism on that continent for the better part of the twentieth century, that he was a favorite of Pius XII who accepted his counsel and respected his achievment on behalf of the Church. None of this is mentioned much anymore. Instead everything is done to besmirch his reputation--just as the Pharisees did to Christ.
Judas was also a "favourite" of Christ's: he was an Apostle. That did not prevent him from falling away: nor did a past illustrious life prevent Tertullian from becoming an heretic; nor Lefebvre & Co. from becoming schismatics.
Willful adherence to the schism of Lefebvre and his TWICE excommunicated bishops (the second one being incurred automatically for consecrating Bp. Rangel of Campos) also places the adherents in the same state of schism and excommunication - all bleatings from the SSPX and associated "independents", Thucites, etc. to the contrary notwithstanding.
