You opinion, I don't care what you feel about it, animals which are raised to be consumed, it doesn't matter, they aren't pets, they aren't endangered species. They are protein. And they are humanly treated for what they are... a food commodity.
You are naive about the wonderful VIOLENCE of nature. It is a beautiful thing, a necessary thing. To watch a bear tearing the limbs off a living deer to eat may not be pretty to you, but it is nature. Animal life is just one giant food chain, it isn't a Disney movie. But agrigulture is not simply the wild nature, but it is necessary, and it is legal, and it is moral. We raise animals to feed people.
Sure, we all go back to just hunting and gathering, and spend all of time and energy just not starving to death. But then we wouldn't have time for internet or TV, or going to yoga class.
Here is a video. The animal rights terrorists are the exact types you are encouraging. They aren't about "humane treatment", they are about stopping all animal agriculture, they believe animals are on a equal level as humans. They believe "meat is murder". They are crazy... INSANE people. Mostly white, all liberal, and CRAZY.
