Imagine if you will, that you are an observant Jewish-American citizen living in a predominantly observant Jewish-American neighborhood. (If you already are an observant Jewish-American citizen living in a predominantly observant Jewish-American neighborhood, you may skip this part.)
Any non-observant non-Jewish-American neighbors are a small minority in your community. As a result, all of the grocery stores, butcher shops, restaurants, delis, and sandwich shops in your community are kosher.
Especially the sandwich shops.
All your life you have been raised with the familiar concept of sandwiches = kosher food: Corned beef, hamburger, chicken, turkey, liverwurst, egg salad, tuna salad, each and every one kosher no matter where it was purchased.
Then one day one of your non-Jewish-American neighbors opens up a sandwich shop that sells ham sandwiches.
You rage, you sputter, you fume. How can this be? you demand. How dare they call that a sandwich?!?!?
Well, it is a sandwich, you’re told. It’s a piece of meat between two slices of bread, mustard and Swiss cheese extra, if you so desire. If you don’t desire, why, every other restaurant, deli, and sandwich shop in your community sells kosher sandwiches; every grocery store and butcher shop sells kosher sandwich meat.
Nobody is depriving you of your right to enjoy a sandwich made of kosher meat.
But you’re calling it a sandwich! You can’t call it a sandwich! You have no right to call it a sandwich!
Actually, we have just as much right as you to call it a sandwich, because like it or not, that’s what it is. What we aren’t doing is claiming it’s a kosher sandwich, and if you want to call your sandwiches kosher sandwiches in order to distinguish them from our sandwiches, you go right ahead.
You’re depriving me of my religious freedom! If I can’t stop you from making ham sandwiches, if at the very least I can’t stop you from calling them sandwiches, you are persecuting me as a patron of kosher meat products!
Do what you want, pal. As per our constitutional right, we are going to make and enjoy ham sandwiches and offer them to anybody who wants one. We won’t try to force them on you, we won’t make your sandwich shops sell them, we won’t make your grocery stores carry ham.
It would be wrong if we tried to keep you from eating the type of sandwich you enjoy.
