Your description of your limited experience with Jack BLood mirrors my own. And that pretty much goes for most of the personalities in the 'movement'.

About GNN...

When I consider the people who spent many hours on that site and then the hostile environment created for 911 Truth there....it's not even a question...

GNN WAS a pioneer for 911 Truth. Lappe' has said this himself and I agree.  GNN still pushes it's own take on 911 and it's pretty lame imo. Sander is part of that take for sure. He's been on GNN for a long time. ANyone remember Delmart Vreeland narrative? Possibly the Second Most Gagged 911 Whistleblower in forever!

Imagine a male version of Sibel Edmonds covered in tough tats and peircings. This version of Sibel is more of a 'in the trenches' kind of guy. He's weathered and untrustorthy after years of underbelly exposure to the sekrit world of spies, spooks, tripple agents and other sekrit things.

Reprehensor was big up on GNN for a long time. So was YT, now known as Cosmos and I'm sure others.

GNN created this video which is what got me thinking about 911...

I'm not sure that sites like GNN knowingly bullshit and gatekeep. Maybe more likely that Lappe' just wants to be 'cool' with Arianna Huffington and Daily Kos...maybe holding out for a Chris Mathews moment at some point.
