It has been particularly bad since the 70s, but there seems to be a lot of anti-Arab/Muslim people in the US. They are the one ethnic group one can racially deride and stereotype without being called a racist. Then you have crazy know-it-alls saying they've read the Koran and that it "proves" Islam is violent, and that that somehow justifies condemning whole different cultures and societies because they don't understand them. These kinds of people are coming out of the woodwork right now because of the shooting at Fort Hood.
