Sex Slavery

http://graphics.thomsonreuters.com/doc/slaves_fatwa.pdf

How is ISIS sex slavery essentially different from Exodus 21, Leviticus 20, Numbers 31, Deuteronomy 20-22, and the end of Debora’s song (“a woman or two for each man”) in Judges 5?

I am trying to reconcile my absolute disgust for ISIS with the fact that the OT has passages that seem to advocate essentially similar behavior.

Thanks,
