Rabonim Crusade Against Sushi
There is only 1 crusade I can see against Sushi:- That it cannot be utilized for Eruv Tavshilin, as it is not a cooked food, despite it being very Choshuv in this day & age to serve at a Shabbos meal, especially in a capacity as entree.
No doubt 200 years ago, no-one would have donned a business suit for Shabbos & Yom Tov, and today it is the most commonly worn Shabbos attire. Likewise Sushi has come to be accepted as very respected food.
