Universal Standards of Civilization

Universal Standards of Civilization: "Outrage as cleric weds girl, 12" : So who gets to decide what's the appropriate age for a "girl" to get married? who says it's 16, or 18, or whatever? not to mention that the rates and time of physiological and psychological growth and maturity varies according to geography, climate, social traditions, etc, is it that bad for a girl to chose to satisfy her sexual curiosity and needs within marriage lock instead of going off and getting pregnant without either a husband or anything to her name? At least we know that she isn't forced to marry (since it's against Islamic Shari'a), unlike what might happen if she reaches sexual maturity and turns to the wrong person which could result in rape or something as bad. ah PLEASE! just leave it alone and try thinking about solving ILLEGAL polygamy in the US. Why is it really Illegal and why is it practiced all the same?
