Turkey's EU membership was rejected because Erdogan is an Islamist - Islamism is fundamentally incompatible with the ideals of modern civilized societies. Gender equality, free expression, and freedom of association are not a function of cultural relativism - they are values that separate advanced civilized societies from uncivilized regressive regimes. Look at the state of individual freedoms of the 57 members of the OIC - it's not a coincidence. Ataturk's values held for almost 90 years and it has taken an Islamist under 10 to regress Turkey towards an authoritarian Islamist regime. When Islamist punks can attack people for listening to music and the police do nothing because they were "provoked" - it highlights the scourge of Islamism.
