Muslim (the majority) is often a bunch of simple minded and silly people, their quran forbids them to think because by quranic narrative that behavior can led them going astray (questioning Allah and Muhammad). And their eschatology is following quran & hadith to go to jannah, muslim never aim to be the greatest : there's no point being the greatest but then go to hell.

And thus I cannot believe for once that 911's 'key activity' is ever done by Muslim. Nonetheless I never doubt the cult of Islam hates western people the most and they're involved.
