Iran clarifies – we don’t discriminate against non-Muslims, only against women! The new law replaces the one passed in 1982 dealing with women's clothes. That law imposed the hijab and focused on the need to force women to cover their hair in public. The emphasis on hijab was based on the belief that women's hair emanates an "evil ray" that drives men "into lustful irrationality" and thus causes harm to Islam. It also envisages separate dress codes for religious minorities, Christians, Jews and Zoroastrians, who will have to adopt distinct color schemes to make them identifiable in public. The new codes would enable Muslims to instantly recognize non-Muslims so that they can avoid shaking hands with them by mistake, and thus becoming najis" (unclean).
