@LUHE: "...so, where would they live? Who would have them?"
They would basically live where they were until their dislocation. The Yazidis, as I mentioned, are ethnic Kurds so they would live in 'Kurdistan'. The Christians, to my knowledge live mostly in northern Iraq In, I believe, in mostly Kurdish territory. I don't think, though I'm not sure, that the Kurds would persecute them. Christians and Yazidis were mostly left alone until ISIS came along.
