So apparently Iran has decided that it may take a page from the old Nazi handbook and start marking Christians, Jews, and other religious minorities. This report mentions that christians might have to wear red badges and jews yellow badges. It may not seem anything other than odd at first, but it's way of dehumanizing and grouping outsiders, which is always a dangerous thing. Iran already has enough hate towards Jews and Christians as it is. They don't need people with targets on them walking around.
