One of the things I read about Vigano was that he had let go the issue of one particular abuser he had been asked to deal with while in the States, which wasn't encouraging. The letter he had published fitted in with two documents I have come across from people who I had reason to suppose were being treated for mental health issues. One I am sure of, a friend with schizophrenia, usually harmless, but with detailed fantasies of how life is organised. The other was a letter which turned up via the Guardian after I had a letter on education published. I have yet to decipher it, but it didn't include any references to new world orders or international bankers.
Something about the syntax of Vigano's piece suggested it was not thought through with intelligence fully engaged. Being able to point out the anti-semitism was helpful with the person who thought he was worthy of respecting.
If all Popes were like Pope Francis, I might abandon my objections to surrendering my conscience to one man. From the calibre of his enemies, he seems to be on the right side.
