Well, in the same week this guy contacted me about his change of mind (he thanked me today for the encouragement), I discovered that Dylan Avery - who was, in 2006 arguably one of the most influential young truthers - has officially given up the idea that the Bush administration was behind the attacks.
That's big news, and very bad news, for the 9/11 Truth movement. The hard evidence suggests that the debunking (or, for Chris Mohr, 'rebuttal') efforts are paying off. Sure, I get a lot of hardcore truthers who spit venom on my channel, but I get a lot of supportive visitors as well.
And here at the JREF 9/11 Conspiracy subforum, true skeptics (who can think critically, that is) outnumber the 9/11 Truther-myth believers by a wide margin. So 9/11 Truth is failing miserably at convincing skeptics of its claims.
I think if you look at the arcs of Heiwa, Tony Szamboti, Major_Tom, Niels Harrit and Steven Jones on this forum, they have utterly failed to demonstrate that a controlled demolition took down the WTC buildings.
The Harrit/Jones paper, in particular, has had ZERO impact on the engineering profession or the scientific community. It just is that irrelevant to the scientific discussion of the collapses, which has frankly moved on and accepted the NIST recommendations by and large.
ozeco recommends changing my reference from 'truther' to 'troll'. I'm happy to do that, and heartily agree that the only people left 'arguing' for 9/11 Truth are essentially trolls, unable to present any new information.
Yesterday marked 10 years of failure for the malicious myths of 9/11 Truth, and firm evidence that science and reason are overwhelming this cult movement, as it should be.
