"Never Forget 9/11
Religion was the cause."
Was it religion? Or was it five decades of reckless interventions in an area of the world that disagrees with our political ideals and resisted our uninterrupted meddling? Or was it our bombing of countless civilians all over that part of the world? Or our sanctioning of Iraq that strengthened Hussein's regime while killing over one million Iraqis, half of whom were children, and creating the strong and difficult-to-counter-because-accurate impression that the US doesn't give a shit about human life when that life is middle eastern? Or was it our constant supply of arms and political support to brutal dictators and our constant opposition to genuine popular uprisings? Or our direct support and funding for Israel's invasions, occupations, tortures, and general assortment of war crimes? Or was it, as Robert Fisk says, "American missiles smashing into Palestinian homes and US helicopters firing missiles into a Lebanese ambulance in 1996 and American shells crashing into a village called Qana and about a Lebanese militia - paid and uniformed by America's Israeli ally - hacking and raping and murdering their way through refugee camps"?
Well, Christopher Hitchens and Sam Harris assure me that Muslims have surrendered their humanity by believing irrational things, and since I hate reading, I should take them at their word and assume that all the bad things done by Muslims are done simply because of their inferior belief system. As a young white male anglophone atheist, I have clearly reached a level of enlightenment where I can denounce and disregard entire cultures because they do not cohere with the definition of rationality that I invented a few months ago.
