Sean, you gave some rational reasons for "Bennyvacantism". However, the Indulters who accept that position aren't going by any of those reason, but rather the reason I gave:
Pope Benedict freed the "Latin Mass" somewhat. For them, there's no Crisis in the Church, just a hiccup in the implementation of Vatican II. "Vatican II has never been truly implemented" and all that rubbish.
If they have the Latin Mass, they are ONE HUNDRED percent happy. See, I wouldn't be. Not until the FAITH ITSELF is safe again in Rome.
