That may play a part in their willingness to kill themselves while taking out Jewish or American folk, however, it certainly does not explain what initiated their hatred towards us. We worked along side Osama Bin Laden not all that long ago. We were we on good terms then? Why don't they target any other non-muslim country that is closer to them?
A better explanation looks to sanctions (imposed by US or NATO) which cause poverty or almost constant US military action on muslim soil as reasons why they don't like us. Lets not bury our head in the sand and pretend they hate us because we have women in the workplace or some stupid reason like that.
