FFS remember BSE? Cows live on grass, they certainly don't eat meat, definitely not other cows, but what we did, in the UK, was boil up their mum and dad's brains and spinal cord and feed it to their kids. For some completely fucking unknown reason, and it unleashed an awful neurological brain disease across the nation and beyond... Which we got away with because it wasn't as infectious as first feared. Still couldn't export beef for a decade because of our dirty bastard weirdo farmers.
It's hardly just a Chinese thing to be this fucking weird. I mean turning cows into cannibals is way more weird than wanting to eat snakes. I hear you can get rattlesnake on the menu in florida, right next to alligator and muskrat. Eating local animals is way less weird than what led to BSE.
