I don't think you have read the book; it's not yet available, right?
I would hope that the book addresses the truth issues, not personalities, just as we do on this forum, religiously (cough) all the time.
If Vere/Madrid present the facts and their argumentation is irrefutable, then it's a question of true/not true.
You know, 0 or 1.
People will take it personally--but that's their problem. Christ wasn't concerned about hurt feelings, either.
Let us hope so. But the title and the advance publicity are not encouraging. Nor is the track record, e.g. Stephen Hand's attacks in The Wanderer, Msgr. Calkin's direct attacks on prominent individual traditionalists, Keating's atacks on Gerry Matatics. And as you point out, on this forum there is a pattern of personal attacks on traditionalists. To give one example, someone recently responded to one of my posts with a message that used derogatory references to "Marcel" at least a dozen times despite the fact that my post had made no mention of the SSPX or Archbishop Lefebvre whatsoever.
