What they do to dogs in Asia is beyond horrific. Even some of the things we see in the US is bad, but doesn't compare when you have a few countries who literally believe that their meat will taste better if the animal suffers more. Like being skinned alive or boiled alive.
In general, people are okay with eating meat until they find out how it was raised and killed. Then you might become bothered by it.
I also don't think, or care tbh, if it's ethnocentric to be against eating dogs or cats. In Asia, there are a lot of people, especially the younger generations, who are horrified by the thought of eating a dog or cat. When they choose to eat dogs/cats it is NOT out of survival, in Vietnam, dog meat is basically bar food that goes with your beer. And dogs are a particular species who suffer because of that "it must be tortured for it to be tasty" mentality.
