Over the weekend we had a very civilized discussion about tribal stupidity (prompted by the Dietrich Bonhoeffer essay), and the reason it didn't descend into CW is that no one provided any examples. The instant anyone gave an example, the particulars of that example would have taken over.
So I can appreciate the desire for citations, but you have to realize that if he'd provided any, everyone would have just argued about those.
On the other hand it's easy to think you're pontificating wisely but you've become untethered from reality. Absolutely it's easy for broad discussions to get distracted by lawyering examples, but the GGP made a specific claim, so they invited the request for evidence.
This reeks like Conspiracy Theory all through. And if it is legit, that is a pity, because most, or many people will dismiss it for "quacking like a Wacky Conspiracy Theory".
