The reason behind the development of the Oppressed theory in Hijab is a modern time phenomenon.
Usually, western culture or especially European liberal thinks the hijab is a sign of oppressive Islamic culture. And Muslim usually blame western culter for not understanding
Some arbs countries, Iran, Saudi Arabia and especially Taliban Afganistan forcefully imposed Burqa as a women national dress. What is not even Islamic law.
Islam is the religion of submission not forcibly imposed law. If women choose not to wear hijab in Iran and ArbsHijab. they ware punished what have no historical relevancy and not a Law of Quran. So the blame is not to west its a blame to the Muslim.
