It's the law of the land. Just like in "Islamic Republic of Iran" where you hail from, "it is the law of the land" of strictly secular France that students must adhere to a very strict dress code. So secularism vs theocracy. Horses for courses. Except of course the French will not shoot buckshot at the school girls violating the "dress code" and blind them.
National culture and character is not a "political" matter. It has nothing to do with "democracy". The national symbol of France is a woman leading a secular-masonic revolution with her tits hanging out, for God's sake.
