Ex-Muslim and son of imam: Islamic State following “steps of Islam’s prophet Muhammad to the letter”

As opposed to the "nothing to do with Islam" crowd, who claim that the carnage and mayhem being done in the name of Islam by groups like ISIS, Boko Haram and the myriad other Islamic terrorist groups have "nothing to do with Islam" or are "perverting Islam" (e.g., and Obama and John Kerry and Cameron), in contrast to all those apologists,  here is a clear rebuttal of that nonsensical proposition.
H/t to JW.
