That's not really true when it comes to Jews though. Jews can be either religious or racial, or both. If you are born into a Jewish family, but later denounce the religion, you are still a Jew. If you are (for example) white and British, but you adopt Judaism, you're not really a Jew, and there are other Jews who you wouldn't be permitted to marry. My point is that the whole race/religion thing is muddled up and you can't always distinguish the two. Besides, I am not sure that this conflict is because of the Christian world vs the Muslim world. It's about the (middle) East vs the West. There's no point hating muslims
