n0mesorah,
“I really think that fighting over proper belief is simple minded. Do you disagree?”
I sense a bit of Jonathan Swift in your responses. So yes, who cares on which side we open our eggs. However, if not for a belief in Hashem, that He created the world and that He is actively guiding the world and sees us and what we do, why do the mitzvos at all? I have non-frum relatives who R”L do not believe that the mitzvos are important. And I can’t let them cook unsupervised in my kitchen. Not because they don’t respect the mitzvos for my sake. On the contrary, they are very respectful, they check hechsherim, they ask which are milchig and which are fleishig keilim, etc. So why not? Because kashrus accidents invariably occur, and because I believe in Hashem and that the mitzvos are actually vitally important, I want to know about the kashrus accident, even if it means a big inconvenience, loss of the food, or even losing the keilim. But my relatives don’t think that kashrus is such a big deal, and being nice, don’t want to cause me “unnecessary” stress or inconvenience. After all, the Torah says not to distress other people, right? So they will likely not mention the accident at all. No harm, no foul.
