I love it when people gatekeep, especially without understanding the history of the California roll and it's role (pun intended) in introducing sushi to the west.

Wasabi and soy sauce is one of the finest slurries known to man, and if we all followed the canonical way to eat food then some of the finest food innovations would have never been invented.
You can say goodbye to Nachos, Burritos, Barbecue, Pizza, Banh Mi, Kimbap, Egg Rolls, Cheesecake, Cheese Steaks, Hot dogs, Corn Dogs, Tikka Masala, Garlic Naan, Drunken Noodles, Halal Carts, Doughnuts, Hamburgers, and basically all hte good food on earth.

Let food evolve, if you want traditional sushi you won't have a hard time getting it.
