A quick google search of the title revealed hundreds if not thousands of "alternative theories" to major events. Some very common ones that have been 'done to death Ad Nauseum' on this site. Others that (in my limited experience on CT's) I had never heard of. I visited some sites and the only thing they ALL seemed to have in common was the total lack of tolerance towards those who chose not to believe the CT, often resorting to name calling and questioning the individuals intelligence and parentage. It wouldn't happen on SB, would it?
Me, call me a sheeple if you like, have an inbuilt suspicion of rampant Conspiracy Theorists.
