I think we need to check their web surfing history and see if they frequented sites like huffington, dailykos, crooks and liars etc. This may help pinpoint what inspired them.
Also, their radio listening habits. Are these guys the four listeners that Air America actually can lay claim to?
Just butting into this thread, there was a link from another thread, that mentioned they had "starred" in a documentary. Do you know what kind of documentary? What about? That might shed light on their motives or at least what kind of idiots they are.
