Dear lady,
Islam has always sanctioned crucifiction - among other things; like cutting-off opposite foot and hand, cauterizing the wounds, blinding the individual and throwing him on hot rocks to die of thirst. Tying someone down and building a fire on his chest is also sanctioned. Castration is common. Female captives are invariably raped - except those pregnant or in their periods. Beheading usually follows when the "holy warriors" get bored with their play on male captives; they just pass around the females.
I wonder where we get off trying to impose our idea of humane treatment on people who do not subscribe to the "Golden Rule"?!!!! "Humane" treatment is a very personal concept and we know how Muslims treat those in their power. Communication requires a common understanding: we don't move into a tribal area and insist they follow rules from our culture, we adapt to theirs when dealing with them. Why should dealing with Muslims be any different?
