Ahh, were it not for religious examples of sexism which have already been proven to support and initiate the ills you called horrific, we would not need to address such ills.  Our example that women are less sacred than men by not ordaining them equally to priesthood and all other levels of ministry, including the papacy, are what creates, poverty, genital mutilation, slavery, rape, global violence, child abuse and even terrorism.  To get rid of the global ills, you must first get rid of the examples, in religion, which gave birth to them, in the first place.
