I've heard that too a few times, as with almost if not every one else. I have yet to see convincing proof of anything. We all have our blind spots and/or taboos we won't discuss.

It might be amusing to come up with a spectrum for truthers. Say from James Corbett to Alex Jones. Or maybe they go in the corners and we need another couple for the other two corners on a grid. Or maybe instead of them, we have certain truther values. I don't know who you'd trust to rank them. Almost any form of voting or polling can be rigged and will doubtless be biased by whatever groups you appeal to participate. And of course there's a difference between seeing a few videos/reading a few articles, and being familiar with dozens if not hundreds of samples of their works - or not even hearing of them, or worse, thinking that you might have heard of them and stabbing a rank at that suspicion in the dark. Nonetheless it would be fun.
