In my opinion, he should be as gracious to Fr. Wathen's supporters as he was in his e-mail to me. In other words, he should sign up for CathInfo and explain everything, including answers to your questions, which I believe are quite legitimate.
This is the Traditional Catholic world, after all. We understand how the Church has enemies -- fierce ones. Supporters of Fr. Wathen understand this as well as any Traditional Catholic!
In the Traditional Catholic world, trust is in short supply, and actions speak louder than words.
If he does NOT go out of his way to foster good PR on the grassroots level, this Fr. Wathen Foundation will come across as another Disney, Viacom, or other big media label that threatens unemployed college students with legal action when they try to post 3 minute movie clips on Youtube. No one likes Goliath; everyone roots for David.
