David the Grifter has hoodwinked his sheep at every turn, including Shanksville. This is on topic. He's never corrected that lie, and continues to spread it.
Has he now 'Fraud? Which time? He's retracted and retracted the retraction multiple times. The last I read he was back on the no-air phone bit, which is a godsend.
That's the latest I have seen too. He retracted his retraction. Even other truthers criticize his writings and selective logic.
Sounds like you are following in the footsteps of our gone but not forgotten "friend". It's not an "insult" to ask for proof of asserted credibility when the people in question(David Griffin and Jim Fetzer) for all proposes have no credibility. BTW a search for unification church fetzer will yield interesting results...
