Censorship and Islam

In the Arab world there are a number of restrictions and prohibitions that seem to be wild and incomprehensible. And they are connected not only with religion, but also the culture and traditions of these peoples. And many things we are familiar with you, for them under complete prohibition. For example, any advertised in these countries, the foreign goods have been fully adapted to local cultural and religious framework. Force. No options.
For example, the Crusaders during the Crusades left a wound in the psychology of the Arabs, so far the image of the cross is completely forbidden. Even the International Red Cross working there under the sign of the red crescent.
