The Arabs who hate the West believe they've waited years to get at the people who they believe have hurt them. So, 9/11 happens, they cheer.
Osama bin Laden is not only an admitted figure in 9/11, but an admitted figure in terrorism in general, who claims to have played a major leadership role in an organization responsible for a great majority of "Islamic" terrorism against the US.
The majority people who died on 9/11 were, at worst, greedy, relatively few of them had any sort of leadership role, none of those killed in the major effort had raised a direct hand against the Middle East or directed others to do so.
If, and only if, we were discussing the attack on the Pentagon, would you have an actual equivalency. But encompassing the entire 9/11 attacks, it falls apart. Those who cheered it were willfully ignorant at best, and you may not excuse them on those grounds.
And your effort to use McVeigh as an equivalency is equally inept. You demand he make an eye for an eye, while at the same time claiming that a soldier for a soldier is justified in 9/11. Your argument is internally incoherent on this subject and at the least needs to be heavily refined.
