Good grief. Connecticut is right next to New York City. If you want kosher stuff, just get in the car and go to New York City. When I was doing construction in Charleston, we used to go into the local Piggly Wiggly and they had kosher food. Stop n Shop is not the only kosher outlet. As to what Jewish Law has to say about crossing picket lines or patronizing stores which have picket lines, I don’t know. It never came up in my experience. The alleged “well-settled law” sounds made up, however, by some leftard Reform Rabbi.
That’s what you get from the left, when EVERYTHING is subsumed to the Social Justice War. They do it to Jewish traditional practice. They do it to Christian gospel.
To make everything about the Social Justice War is to lose the very principles that it was supposed to be about.
