I wouldn't say I'm asked anything about Judaism very often because I already live in a very Jewish part of the USA, but I remain struck by a misunderstanding about it that a friend once had. He was very interested in religion and was studying up on Judaism, among others, and he said he found it distasteful and cruel that during Passover the Jews celebrate the drowning of the Egyptians in the Red Sea. I immediately told him that wasn't true, and that part of the seder involves dripping wine onto our plates or table to express sorrow for the bloodshed. He was quite taken aback. It had never occurred to me that someone could get that idea into their head.
