Why do only Han people eat dog meat?

The climate in the north is cold, so Koreans have a tradition of eating dog meat since ancient times. But Han people and Koreans have always lived in harmony, and no one wants to offend the living habits of Koreans.

Muslims all over the world don't eat dog meat or pork, but the Han people get along well with all Muslim ethnic groups, and they have never seen Muslims protesting that the Han people eat pork or the Korean people eat meat. This is the purpose of respecting each other's living habits and living in harmony.

Some people say that dogs are friends of human beings. I have no objection. I like dogs very much, but animals are friends of human beings. We shouldn't favour one over the other.

Some people say that dogs are pets, but I have no objection. I used to have dogs, but cows are the benefactors of all mankind. Without cattle, there would be no human farming civilization for thousands of years. In front of pets and benefactors, who should we have more feelings for to conform to our morality? Obviously it should be a cow.
