I suppose if that were the case it wouldn’t but it’s really not worth the argument tbh. They’re both bad enough. Also it’s not the case, the cow still has to do slave labour.
Milk production is labor. And if you’re gonna disagree I would direct you to my wife but I should warn you of her right hook lol. Although she is very tired these days from having to produce all that milk for our baby so maybe you’ll get away with it. Also most cows aren’t on pastures. You literally can’t see most cows.
