Classic, SSPX schismatic thinking. Double down on rebellion against legitimate Church authority and accuse Rome of being schismatic. This is also classic Jewish behavior.
The sooner the SSPX realizes the Vatican is not interested the better. They need to go on the offensive with their messaging by taking the fight to the heart of the matter: denounce Leo as head of the conciliar church, accuse him of being in schism with the great popes of the past for adhering to the Vatican II false religion, declare it is Leo who is 'canonically irregular' with the Catholic Church not the Society, and state that it would be an honor to be 'excommunicated' by men who approve of gay blessings and LGBT pilgrimages. 💪
