The United Arab Emirates recently cautioned citizens not to wear "traditional Muslim" clothing when travelling abroad because it opens the wearers to misunderstandings or attack. Just last week, a fellow speaking Arabic in an Ohio hotel lobby was arrested after a worried clerk called 911. Responding cops tackled him on information that he was actively pledging allegiance to ISIS.
Welp, here's the article if you're interested. I can see where the hotel clerk would be a bit concerned or even ask for an officer to bring in an Arabic translator to make sure everything is ok if the fellow seemed agitated. And yeah, I do agree that the full-face veil is a bit threatening in Western society for various reasons (most of which have little to do with Islam per se). I don't care what religion you are, you can't pull that crap in a bank. You just can't.
Mixed feelings. Obviously I can't go to their country and wear a bikini, either, so maybe the courtesy works both ways. Hate that people would feel threatened, though, while they're off minding their own business.
