Great write-up. Reminds me of what someone once related, that pigs are hybrids of humans and boars, bred to satisfy an ongoing hidden cannibalism, which is why they aren't kosher. I've pondered whether any truth to that. Your approach is from the other direction, but both acknowledge strong porcine/human bio-congruencies.
When once in Bali I was woken to a pig screaming, as though being tortured. I was inforned it was for a holiday feast, the pig was boiled alive. Apparently there is the belief that pigs are incarnations of humans who have accumulated some sort of bad karma. Boiling like that liberates their soul, and is said to, conveniently, make the meat taste better.
