Oh, that one: The Commie Plot Theory of Everything. The theory was propagated by “rrrod,” a colorful old character on the North Carolina forum.
I knew the Commie Plot Theory of Everything was true but after watching the video DJMacWoW posted a link to last night, it tied every loose end together clearly. I have a couple of tiny disagreements with it (one is the wonderfulness of nuke power...) but other than a couple of details, excellent.
