Your posting as AC and seem rather ignorant, but I'll bite.
By definition, all European countries are Christian States. It's not a matter of your opinion. They were founded and remain Christian. Not just in nature, but in law and in decree. Others may live there with equal rights...at least recently...and on paper if not in practice...but that is no different than in Israel. Similarly, Turkey and all ME countries are officially muslim states. It has nothing to do with how secular they are in practice. BTW, seems like you've never been to Israel, but it's very secular both in population and in governance.
Religion doesn't figure into Israeli legislature any moreso than in most countries.
