825,000 chickens per year in the U.S are accidentally boiled alive or drowned before their intended slaughter. https://animalclock.org/ this isn't prevented because prevention mechanisms cost money, as in they eat into profits.

It's standard practice for male pigs to have their tails and testicles ripped out without pain relief https://www.vox.com/future-perfect/23817808/pig-farm-investigation-feedback-immunity-feces-intestines this link also showcases how people abuse pigs for fun. Objectifying animals you kill is a coping mechanism for humans, engaging in that much killing is unnatural and unhealthy for humans, it also leads to vastly higher rates of domestic violence and crime, as it normalizes violence as a solution.

It's normal for foxes to have their skin ripped off while they're alive. Animals have their beaks ripped off so they can't kill each other in distress, as they go literally insane, abandon normal social hierarchies, and start simply trying to kill each other given the lack of space. http://www.nationearth.com/

I understand ignorance of how horrible the conditions are is a normal part of how humans justify our atrocities. However what always baffles me is people who appear genuinely concerned about animal welfare can be so absurdly uninformed on the practices that they directly support with their purchases, while criticizing practices that you have absolutely no influence over in a place on the other side of the planet.
