Archbishop Lebvre was prophesised by Our Lady of Quito Equador.
Meanwhile Archbishop Thuc said the Novus Ordo and recanted his traditionalism and admitted to withholding intention for Sacraments. One of the gravest breaches of trust imaginable by the clergy. Literally even pedo priests dont do that.
But we're suppose to be Chwatable.
Considering your actions and words, Archbishop Lefebvre would be both horrified and disgusted at your behaviour. I know enough about his character to be certain of this.
Even if we assume that what you said is correct (and we have evidence that it is not), sacraments do not become retroactively invalid because a Bishop who was Catholic fell into heresy in his later years.
