Being Jewish, I wouldn't dare go with my yarmulke on and Torah in hand. Would you?
I think you'd probably be fine, actually. There are over 20,000 Jews in Istanbul. But yeah, I'm not saying these countries are perfect but they're all worlds better than the Christian countries I listed on just about every metric. I wouldn't want to walk down a street in DR Congo regardless of whether I'm wearing a yarmulke or not.
