How do you shut up 9/11 "truthers"?

[Fidel_Castronaut]

And how did it start? 911
Same story- different day. Same leadership.

No, actually. Bombing of USS Cole? What about foreign embassies in Kenya?

No, wait, what about the scorched earth operation by the USSR in Afghanistan and the rise of the mujahadeen?

No, wait, what about disenchantment from western ideals in both Egypt and Germany by the leader of the 9/11 attacks Mohamed Atta?

No, wait, hang on. What about the advent of Wahhabism in the Saudi Peninsula in the 1700s? Wait, wasn't that well before the US was even a thing?

So, OP. When confronted with the idiocy promulgated by folk like the professor here, just bear in mind that 99% of the time they know fuck all about context and about how events prior to the given event build a rich tapestry that can be de-constructed to give a much more believable and understandable backstory. Naturally the prof here can go onto wikipedia and do a quick search and conclude that none of the above are remotely linked to 9/11. But then again, he's an idiot, so it's cool.
