Wall, I disagree with you, not about Len so much (that remains to be seen), but the other stuff you said. Some of the people I respected the most of all on another website, took the longest time (some 3 or 4 years) before I finally got them to open their eyes. I kept pounding in the info and something would finally click/stick.
People will believe whatever they're predisposed to believe. In this case, they'd rather assert that pigs can fly, than imagine that our government could be responsible.
About Len, I'm sure he has opinions about different aspects of 9/11, but there's a possibility that you, roguedolphin, and I are making his opinions a little shaky. I could be wrong, but I prefer to think that there is a wee bit of a change going on in his head.
