Maybe +Fellay isn't blind, but knows exactly what he's doing? Maybe his contradictions are not accidents? Maybe they are meant to confuse and tempt?
As Sherlock Holmes always said: "When you have eliminated the impossible, whatever remains, however improbable, must be the truth."
It is impossible that +Fellay continues to make contradictory statements, regarding tradition and modernism, day after day, year after year, by accident.... ESPECIALLY when such comments are not whimsical, or "off the cuff", but are prepared statements, reviewed, thought-out and pre-meditated. It is impossible that these statements are accidental.
Ergo, they are on purpose. Now what is the purpose? The following are the only probable conclusions:
1. He is a modernist, who doesn't realize he is one, and who does not see the contradiction. In this case, he is more dangerous than an actual modernist because he like a drunk person behind the wheel - totally unpredictable and homicidal, except you don't know he's drunk. Yet, you continue to let him drive, even though he's swerving all over the road, because he tells you "he's fine". At some point, you need to force him to stop driving or else you will die with him.
2. He is a modernist, who believes that the society should be 'under rome', at whatever the cost. In this case, he cannot be trusted because he cares not for Truth or tradition and is an outright heretic. He is like a person behind the wheel who intentionally drives off a cliff and TELLS YOU HE WILL DRIVE OFF THE CLIFF - a murderer.
Regardless of which he is, +Fellay cannot be trusted and should be gotten rid of immediately. Or, those that "go along for the ride" will suffer the consequences.
