There is a chilling case out of Port St. Lucie, Florida where a couple allegedly kept a 13-year-old girl as a sex slave while home schooling her in an isolated existence. In a Christian counterpart to ISIS (which has a widespread sex slave system of captive girls), the couple reportedly taught the girl passages of the Bible that they say justified such sexual domination and abuse. Rob Johnson, 44, and his wife, Marie Johnson, 43, have been released on bail (of $60,000 each) pending trial on felony sexual assault charges.
