This is also taught in probably every American university -- that 9/11 was a plot by Zionists and their neo-conservative lackeys as an excuse for America to wage imperialist wars, etc. ad-nauseum. I bet 30% of U.S. college students do not know which countries fought WWII but they are "experts" when it comes to Zionist conspiracies and American imperialism. If all foreign terrorist sympathizers were deported we would still have Gramscian institutions teaching enemy propaganda and it does not matter to them who the enemy is.
On one of the threads about Bosnianmuslims in the USA, a couple of years ago, a poster who worked for some social agency that re-settled refugees from Bosnia, went to a wedding or some sort of festivity attended by Bosnian muslims in Atlanta and was told by some muslims from Bosnia that the JEWS were responsible for 9/11.
