Yet the authority to speak infallibly resides with the Pope and with the bishops in union with them. Showing them disrespect is showing disrespect for the teaching authority of the Universal Church. While not necessarily ex cathedra, there may be considered instances of infallibility since 1950

As for hidden knowledge, you are implying it in your last statement. There will be a triumph of the Immaculate Heart, and all Popes are traditional Popes in that they adhere to Holy Tradition. But when you say “traditional,” it is implied that you mean one that rejects the Second Vatican Council, unless I misunderstood. If this is what you mean, then it implies that you have a knowledge that the rest of us do not have as you are certain of that Pope’s understandings of the Council. Likewise, as for Don Bosco, in what way does this speak of a future “traditional” Pope?
You are using Fatima and Saint Bosco for an agenda, rather than for what their intentions are. Fatima said nothing about a “traditional” Pope, an adjective that is misleading itself since all Popes adhere to tradition. Yet, to gleam an understanding about the Popes that will reign at the Immaculate Heart of Mary’s triumph is taking a personal interpretation, instead of what is actually stated. It is attaching a knowledge that is not known to the majority of people, and is only meant to be divisive; it is meant to criticize the Council, not directly, but through implication. If this were the message of Fatima, then Sr. Lucia would have stated this to any of the Popes during and after the Council. Instead, there is a reduction to grasping at straws.
If we are not united under the leadership of the Pope and loyalty to his office, then Jesus lied when He said that He would build His Church on the Rock of Peter.
