You assume the leaks are all from SSPX sources, I suspect curial as well. Either way, they are still Catholic, they acknowledge ALL of the dogmatic teachings of the Church and the Pope as sovereign. They deserve our prayers, not our scorn, imho of course.
The local folks are quite different from what you describe, and from what they said travel a great distance to periodically attend an SSPX Mass rather than going to Mass at any of the local Catholic Churches. Could you point me to someplace where the SSPX officially distances itself from those who do not accept all the dogmatic teaching of the Church and explains that they do accept all the dogma of The Church?
I didn't see it on the sites I've checked out so far but maybe I missed it because I was reading what they claim justifies their original split.
