You repeat bringing the male preference rule in Islam as if that was again unique to it. Should I remind you about the position a woman is held in Judaism (go see Kadosh about that, it's a good movie about women situation in Jewish orthodox circles). Christian on the other hand were debating whether women has soul or not

The three abrahamic religions, and almost the whole antique world for that matter considered women as worthless. Women emancipation did occur not thank to religion, what ever religion, but against religion.
Muslims will argue that Mohummad actually improved women s condition compared to the situation before Islam. Burying female new borns was common in the Arbic peninsula for exmaple, Muhammad made it one of the worst crimes, and that is why this habit dispeared from Islamic land.
