The fallacy of thinking that pointing out a claim is unfalsifiable is automatically a refutation. While unfalsifiability can be a problem for scientific claims, it's not a problem for all claims. Many important domains involve unfalsifiable claims—and that's fine. The fallacy lies in treating "unfalsifiable" as synonymous with "meaningless" or "false," ignoring that different domains have different standards. It's the mirror image of the Appeal to Falsifiability—using unfalsifiability as a dismissal without considering whether falsifiability is even relevant.
"Your ethical principle is unfalsifiable, so it's meaningless!" That's Unfalsifiability Fallacy Fallacy—applying a scientific criterion to ethics. Ethics isn't supposed to be falsifiable; it's about values, not predictions. Unfalsifiable doesn't mean meaningless—it means different rules apply."
