Force-feeding means they use a weird speculum-like thing to feed them extra food.
In the scheme of animal ag, that is pretty tame. Most animals are kept in tight quarters, are prone to disease, will be killed when they get a disease that would “cost too much”, live in their own faeces… and are then killed so that someone can experience a very specific kind of pleasure when eating them.
Anima welfare discourse like this is sometimes well-meaning but tends to ignore the elephant in the room: what happens to the other animals you eat?
The Soviets killed a bunch of Nazi soldiers after they were captured (fucking good) and put a lot more into their gulag system for 4-10 years where they either died or ended up reeducated. Nazi soldiers were not treated well, though said Nazis were trying to genocide all kinds of groups, including settler-colonizing Russia, and burned, raped, and pillaged their way to Stalingrad, so I’m not going to cry over them under any circumstances.
