The argument works for a Western audience that are okay with killing and eat some animals, but find it abhorrent to eat others. Most people don’t like the idea of dogs in pain, and if we did rear dogs like we do pigs, there would be huge public outcry.
And sure, you get Redditors and Lemmy-ites who go “Oh ho i’d eat dog!”, but they mean they’d try the meat once at a market, to maintain moral consistency. The truth is they’d be just as horrified if they saw dogs yelping in factory farmed cages, like we treat chickens.
But there’s no reason to treat some animals one way, some another. They all feel pain, they all feel misery, they all call for their children once they’ve been culled. It’s objectively immoral to eat meat when not for necessity.
