I don't think I want to put myself into the position of defending Opus Dei because they are annoyingly conservative, but to class somebody a "religious maniac" merely because of membership in Opus Dei seems to be somewhat of an exaggeration.

It possibly is but why do I get the impression that if it were the Spanish Inquisition that was being critisised here - that you would post something to the effect that it was just down to a bit of over enthusiasm or youthful high-jinks?
