You're probably being downvoted for being off-topic, but there's scarcely a place on the Internet you can call out the abuse of animals for our culinary pleasure without getting a lot of backlash. People don't want to think about it.

I became vegetarian after there was a big news cycle about the dog eating festival in China – then I saw pictures and saw that most of those dogs appeared to be treated much better than the animals that are part of the industrialized meat process.

Torture is something, but ultimately we kill them, ending their life so we can eat them. Humans will come up with all kinds of justifications for every part of this process, it's almost not worth arguing, it's like religion in many ways – you're raised eating meat, and it's hard to be rational thinking about why that might be bad, for the creatures being eaten, for the environment, etc...

I was fairly sure that I would be downvoted for being off topic, which is fair. It is possible to buy meat from animals that have been treated humanely (until the end) but in general difficult and expensive. You are correct that it is a touchy subject with people, but I will still annoy family and friends occasionally by bringing up this topic.

I had the misfortune to once actually see a pig processing plant, and that is one of those horrible images you can never get out of your mind.

I don’t see anything in their eyes, but if it’s sadness you see I’d assume it’s from being separated from their comrades or living in confined spaces all their lives.

Poultry are some of the most oblivious animals, I think worse is the effect animals like cows have on the environment.

yes, i remember i was told as a kid of someone who worked in a horse meat factory and the screams of horses were horrible. Also i was told one of the horses went to one of the workers and tapped gently on her shoulder and started doing gesture that said "please spare me" (true story)
