A practical agreement was made between the now Neo-SSPX and modernist Rome.

What is this? Damned if you do, damned if you don't?

No Trento, not at all.
Damned because the desire and intent is still there in those leading the SSPX despite the fact that Rome refused at the last minute to come to the party, and because cooperation is taking place without any signed docuмent.
If an agreement was not reached, it was not through any lack of trying by Bishop Fellay, who preferred obedience to an objectively wicked Pope, destroyer of the Church, to the common good of the Society as he confessed in his letter to the three Bishops.
Had Rome approved an agreement, there would have likely been a large part of the SSPX refuse to follow. Hence Satan's masterstroke, keeping the priests in the SSPX and using the same gradualism that saw all the good priests at the time of Vatican II end up promoting the Revolution.
This is why we now have an SSPX that discourages conditional confirmation officially on its website and nobody does anything about it. Defending the faith and the faithful no longer matter, we can trust modernist Rome to do it. It is one month since Fr Laisney sent my concerns about this scandalous article to Fr Pagliarani, Fr Sherry, Fr Nicholas Mary, and Fr Selengy, expressing his surprise at what was written, yet the article is still there with not a change.
Stop burying your head in the sand.
