Yes, yes ... those are on the individual priests' initiative. What about SSPX themselves, officially? I've seen not a peep out of them.
This.
Some individual priests might be "good", and there are valid Masses and graces there. but the SSPX as an organization, in the abstract, is dung.
Anything good you can point to is from God through one or more priests. The good comes IN SPITE OF the SSPX and its objective evils. The SSPX adds nothing, and only takes away, from the graces given by God through the ministry of SSPX priests.
THEREFORE, if the SSPX were totally dissolved, say they were shut down by the government, sued for 500 billion and thus had to collapse, it would be 100% good, 0% bad, a total blessing for the world.
Because all the priests would still be there, they would still be offering Mass. But the evil organization (SSPX) controlling them towards evil, leading them back to Vatican II, deceiving the people, attacking good priests, putting out propaganda and lies, would be gone. There are other evils the organization has perpetrated, which I won't mention here.
