Female genital mutilation, daughter- and wife-beating, child and arranged marriage, polygamy, purdah, easy divorce for men, female sexual and domestic slavery, veiling, routine rape and gang-rape and honor killing - none of these are unique to Islam. But no other ideology, religious or otherwise, sanctions and excuses them all in the way that Islam does. In the Arab and Islamic world these abuses are considered "normal" and justifiable "cultural" expressions of identity. These facts show that the war we're fighting isn't just about bombs and hijacked airliners. It's also about the oppression of women, often in horrific ways.
