You are trying to not understand. There ARE Kurds in Islamic State Army and they are accepting to live under IS flag. You saying that, you deciding where they're happy to live? And again, there are Kurds in IS and it seems that they are quiet happy. Just google it.
Also, nobody say anything to kurds who fight for kurdistan. They are free to do whatever they want. If they want free kurdistan nobody forcing them to not. Actually many countries support them to do.
The point you don't understand; You can't say IS hates Kurds or IS wants to kill Kurds etc. Like I said in previous post, if you want to be part of them, they don't care about your race or nation, you can be part of IS. IS fights against kurds who fight against them, not all Kurds.
You're not being very clear so it's difficult to understand your position except that you seem to be an apologist for ISIS. I never did say that ISIS hated Kurds because they are Kurds. However their assault on Kobane and annexation of Kurdish territory is naturally going to put them against Kurds. The few Kurds who are on their side are quite the exception.
