I'm well aware of anti-Americanism (I'm French) - I've heard my dad cheer when hearing of the death of American soldiers in Iraq, a Chinese student say that he approved of the 9-11 attacks because of America's support for Taiwan, etc.

(It's funny you mention the Piss Christ; it was exposed in Avignon (here in France) and yesterday a group of catholics forced their way into the exposition, neutralized a guard and vandalized the photograph with a hammer. A far cry from Theo Van Gogh, I agree, but still not a completely pacifist response.)
