Anyone not a muslim is to be either murdered, enslaved, and tortured also before death. It is Islamic theology, as those who study the Koran know.
Islam teaches whatever the local imam says it teaches. That's it's biggest problem - no central religious authority. Tell what you said to an American Muslim and he will strenuously object (and probably call you an "uneducated racist idiot") - because his imam says the Koran means something totally different than the ISIS imams say.
The media is, of course, accepting the Taquiya of the CAIR-type imams without any questions, and calling us racists for pointing out the truth.
