I'm neither Jewish nor Asian, but I do always have a large tin of this delicious Chinese vegetarian barbecue sauce in the fridge with a prominent 卍 on it.[1] It's a fantastic marinade, among other things.
Anyways, it resembles a Nazi swastika enough for the uninitiated to look twice when opening the fridge. It causes me some cringe when I think about it but my Chinese friends and family assure me it's common, has nothing to do with hateful values, and long predates the Nazi use, and ... shrug?
