And another attack against the Muslims in the west, in addition to the almost daily a=occurrences of hate attacks fueled by xenophobia and Islamophobia. The rampant negative propaganda against Islam must be blamed for this particular attack.
I'd blame the muslim terrorist themselves, instead. No need for negative propaganda. A collection of uncivilised early medieval tribal customs, represented by a big bunch of savages can earn a bad reputation on it's own.
