Title here is a big problem. It is a parody of the Snow White fairy tale, in which the magic mirror would respond to the question, “Mirror, Mirror, on the wall, who is the fairest one of all?” Forgetting about the magical thinking stuff that energizes fairy tales, but mirrors do reflect one’s appearance, and can thus “have an opinion” about who is the fairest of all. But “frum” has zero to do with appearance. The latter matter is an obsession that is common in our generation, where someone’s Jewishness is determined by a boy wearing a white (not colored) shirt, and other similar stupidities. The focus on appearance completely ignores the need for someone to connect emotionally and mentally with HKB”H, and uses judgment of these nonsensical trivia to judge people. And this risks leaving kids in the street without yeshivos and schools, not giving aliyos to mispallelim, and other forms of rejection that are clearly anti-Torah. We are all בנים למקום. We would not throw our own children away. We would fight tooth and nail if someone grabbed any of our children to discard. But we somehow have clear consciences about using meaningless and irrelevant criteria to reject HKB”H’s children. We have a huge problem, and I suspect that our golus requires us to fix this if we want to merit a geula.
So if your mirror could speak, and it spoke of frummer, break it.
