But the majority of us loves our animals
And when the milk production drops, the vast majority of dairy cows get their throat slit and their bodies sold for profit. I surely wouldn’t treat those that I love that way, but I guess animal farmers just have a very different concept of “loving animals” compared to people who have pets, for example.
I think most people would actually consider factory farming unethical, they just put the blame on the producers for treating animals like shit. And the producers are locked into a race to the bottom for competitive prices, so they’d blame the customers/market conditions.
