I'll just quote Peter Tatchell for context:
Large parts of Iraq are now under the de facto control of the militias and their death squad units. They enforce a harsh interpretation of Sharia law, summarily executing people for what they denounce as "crimes against Islam." These "crimes" include listening to western
pop music, wearing shorts or jeans, drinking alcohol, selling videos, working in a barber's shop, homosexuality, dancing, having a Sunni name, adultery and, in the case of women, not being veiled or walking in the street unaccompanied by a male relative.
