"Who said sex-slavery is over? What—because the UN said so?"

While this may be the first sex slave marriage to take place in Egypt's recent history, it is certainly not the first call to revive the practice. Earlier, Egyptian Sheikh Huwaini, lamenting that the "good old days" of Islam were over, declared that, in an ideal Muslim society, "when I want a sex-slave," he should be able to go "to the market and pick whichever female I desire and buy her." Likewise, a Kuwaiti female politician earlier advocated for reviving the institute of sex-slavery, suggesting that Muslims should bring female captives of war—specifically Russian women from the Chechnya war—and sell them to Muslim men in the markets of Kuwait.
This is the kind of crap we and muslims who want to live in the modern world are dealing with. And which most of our media don't want to say a word about.
