Like they do with dogs today.
There would be social pressure in China to stop eating pork so as to do civilisation better.
And nobody would ask why the Bible forbids eating pig meat; since pigs wouldn’t be food animals, asking why it’s wrong to eat them would be like asking why theft is wrong.
Isn’t this the exact same conversation Vince and Jules had in the diner in Pulp Fiction?
But yeah, I totally agree. There would have to a huge increase in pet pigs before it got to the same level as eating dog.
I hear they are very smart and make great pets, but I imagine most people would prefer something fluffier.
