Don't get me wrong, 9/11 was certainly a devastating horror and the impacts were huge - I was just pointing out that the larger number of deaths (consensus is that around 3400 black people and 1400 white people were killed by the KKK or other racist groups that were part of a wave of anti black terror [correcting myself to my comment above that it was all attributable to the KKK]: http://www.politifact.com/punditfact/statements/2013/nov/27/... ) and on the whole the conspirators were American born terrorists with a single goal in mind. This lynchings took place over many many years, but the affect on the black population would have been massive and the social and economic effects can still be felt today. Thankfully the western world doesn't see anything like this today.
