No demand then this kind of sadism would not happen.    The factory farming animal industry is a big nightmare for animals overall pigs are kept in tiny stalls so they cannot move,  baby cows are taken from their moms at birth so the moms produce more milk for human consumption (note dairy is not even healthy I have many of the relevant studies), they then are killed for veal if male or used for dairy cows if female.     I am vegan absolutely there is no way anyone can effectively argue even so called humane raising of cows/chickens/pigs is o.k. as the slaughter of them is just a nightmare as well.   So many people are completely dissociated from the reality of it.   But I know many people whom are now vegan or vegetarian whom were not even a few years ago, which is promising.
