And he wasn't conditionally ordained?  So if the faithful go to receive Holy Communion at Sanford, they might be faced with doubtful Sacraments (if they hold the NO Rite of Ordination to be doubtful).

If an older priest ordained in the New Rite by a bishop consecrated in the Catholic Rite, would that not be acceptable? 
I would hope that is the case. I may not be as wise as them, but the New Rite consecration seems ambiguous. It was after all a portion of an Oriental Rite, wholly valid in context, but ripped out of context by Mgsr Bugnini VC. In the case of priests less is more. Poorly formed (many in the sixties even with the old Rite were that and are now raging Modernists) priests do extraordinary damage.

I’ve been told that the SSPX Seminary under Fr. Leroux has been teaching the seminarians that Fatima is just a private revelation. That is what all Novus Ordo non-believers say, “just a private revelation”.
 
Saying it is just a private revelation is code for saying it is not of any importance, that one can take it or leave it,  like Akita, or Divine Mercy  “revelations” to Sr. Faustina, or Medjugorje, doubtful revelations.

Um, this is true. Fatima is just a private revelation. One can take it or leave it. Saying it is a private revelation is not the same as saying it is a false revelation, like the other "apparitions" you mentioned. Those are outright false. But Fatima is not a public revelation, as those ceased with the death of St. John the Apostle. No revelations from heaven after that point are obligatory for Catholics to accept.

What you say is technically true, however, the SSPX should not downplay Fatima or any true revelation by using the adjective "just".
Fatima is not "just" a private relation but an extremely important private and prophetic revelation. If Our Lady told me during WWI that a worse war will break out during a the time of Pius XI (yet the Pope is Benedict XIV), and then several years later a Pope named Pius XI shows up and sure enough another World War comes, then something in me will say "I think I better listen and do what She tells us".
