What was it he was talking about?
As a Catholic I'm not offended that he called the pope senile. I don't know if he is but he appears to be at times. My own mother is senile and I wouldn't take offense if you noticed it either.
Character attacks - "no-name" (Svett?) was an anti-Simite and anti-Catholic simply don't cut it unless you can source and provide documentation for what you are stating.
What you are referring to - I believe - is that Dr. Jerry Corsi (co-author of Unfit for Command) has been unjustly denigrated in this way to try and take away from the success of the SwiftVets.
So, you've mis-heard, mis-represented and misspoken. Maybe.

He is a believing Catholic who correctly pointed to the Pope's age as having caused him to fail to act promptly and decisively on the homosexual scandal and correct it in a timely fashion. That puts him in the company of millions.
