Sushi as entertainment? Then Birthday cakes are out, Pizza for sure, and no more macaroons, those are dry anyway. Rice is a staple for the majority of the World’s peoples. Rice made its way into shas and poskim. I grew up in the ’60s, rice was a staple; it was not an entertainment. When you have rid yourself of the really treif entertainment, e.g., movies, tv, internet, videos, then you can start working on people’s pallets.
