I really don't see anything wrong with eating animals. Humans, like most animals, are carnivores, and it's natural to eat meat. However, in modern society, farms do the bare minimum. For example, if I was in the wild, I would eat meat, by hunting. They lived a fine, free life, and when I killed it, that's that. But farms make the animals suffer to the worst their entire life, and it's fucking disgusting. I'm not asking anybody to stop eating meat, just asking the farms to make the animals have a better life before they slaughter them.
Thankfully, there are still some organic farms, and I encourage my parents to buy meat from Whole Foods.
I also punch people whenever they say they just ate at KFC.
