Even sadder is the fact that (according to a recent Algerian speaking at TED), while westerners are calling all Muslims (and Sikhs) terrorists, they ignore that 85% of the direct victims of terrorism (ignoring USA drone strikes etc) are non-fundamentalist Muslims in Afghanistan, Algeria, Egypt, etc.
People are going to be racist and xenophobic assholes no matter what unfortunately. Anyone outside of their race / religion / country will be hated upon with the fire of a thousand suns.
