You can't live in the 80's. It was a great time, no smartphones, etc. but a lot has changed since then.
+ABL had to try. He tried once for all of us -- his efforts made it clear, to himself AND to posterity, how far gone Conciliar Rome was.
So if someone 10 years after +ABL did EXACTLY WHAT +ABL DID, this second-timer would not be as blameless, wise, OR innocent as +ABL was. Because he didn't do it first; he should have known better. He would be an imprudent fool at best, and a traitor to Tradition at worst.
And this is 100X as true when the Church is in the state it's in today, with Pope Francis at the helm. How can anyone suggest (with a straight face) that +ABL would say (if he were alive today), "Yes, things were pretty bad under John Paul II, but we have Pope Francis now. Looks like the Crisis in the Church is wrapping up. Awesome! Time to put ourselves back under their authority." Have you lost your ever-loving mind?
Remember, it wasn't just +ABL that was "burned" trying to talk sense into Rome. How many Traditional organizations have made a deal with the devil and were completely neutralized/destroyed?
Imagine a terrorist holding 30 people hostage in a room. The first person to attempt escape is killed by gunmen outside the room. Then a few other people try the same thing at night -- same result. At this point, trying to escape is basically a death wish. The first guy didn't know it would kill him. After several have died due to the "armed guards outside the door", everyone remaining SHOULD KNOW BETTER.
Imagine the group gets down to 10 people, the other 20 being killed trying to escape. A few days later, a man decides to make the 21st attempt to escape. His name is Bishop Bernard Fellay. Is he wise or foolish?
