Turkey is a secular republic, according to its Constitution. This means religion and state must be kept apart. It also means the state has to remain equidistant to all faiths, or lack thereof, and to protect the liberties enshrined in the international agreements the country is party to, if it is to be true to its claim of being a genuine democracy.
These liberties include the freedom of expression, which Turkey has never been good at protecting. They also include respect for diversity, which Turkey has never been good at protecting either.
