As was said earlier - validity of the sacraments doesn’t hinge on the predisposition of the individual priest. That still doesn’t absolve Fellay et al of their decision to defy the Pope.
Where and when has Bishop Fellay defied the Pope? The bishop has balked, so far, at signing off on some funky double-secret profession of faith in a purely pastoral council that goes against tradition. But that same profession of faith has not been required of the converting Anglicans.
Bishop Fellay has called for three Rosary Crusades, either for the Pope in particular or the Catholic Church in general. What has your bishop done?
