Death threats in order to achieve peace - sounds like a contradiction doesn't it!?
Except when we see that the peace that Islam is talking about is something akin to Pax Romana which is the peace in the Roman Empire that was achieved, for a brief period, when their enemies were killed, silenced, subjugated and basically conquered in every respect. In this regard yes Islam is the religion of peace, but a very different peace to the one that the civilized west understands it. But the double speak works for them like the forked tongue
