I'm from the former Eastern Bloc. Not playing with a toy gun as a child is seen as weird. It's something that never happens, everyone has used a toy gun many many times and never ever thought it's wrong.
Same deal here in at least some (most?) parts of the US (the vocal minority of overzealously-violence-averse helicopter parents notwithstanding). Cap guns, squirt guns, Nerf guns, you name it, we had it (and to my knowledge still have it). Such toys are increasingly-frequently disallowed in schools, but they're still prevalent in homes and toy stores nationwide.
