Normally, I'd let stuff like 9/11 trutherism go and completely ignore it.
It's disgusting videos like that being passed around that convinces me truthers are vile scum and should not simply be ignored, they should be vociferously opposed at every turn, exposed for what they are and forced to explain how online actions such as putting a video like that together somehow equals any noble pursuit such as seeking justice for the victims.
Oh, we're sounding another funeral dirge for the "official conspiracy theory" now, are we? How many times have we heard that line before from truthers? Over how many months, or years?
Galileo tried the same thing just a few days ago with the garbage Jones pay-to-publish paper. Every few weeks, truthers try to declare that "it's over", and they fail 100% of the time and are left to make excuses for why they fail 100% of the time.
