I would hope that most people who have seen much of anything about industrial ranching would have a hard time not showing a bit of empathy.
Some descriptions of hell aren’t as upsetting as seeing how those animals are kept and handled.
I only ever see meat eaters argue about what the body needs or how our teeth are meant for meat. There is no way to argue that the modern meat industry isn’t horrific, I think some carnists that react strongly to vegans unconsciously know this and react with anger because of guilt and shame.
