In my opinion, It is difference of culture.

I think that It is very difficult topic for discussing.
I can't understand people who eat dog because I love and raise a dog.
There are many another things for health.
However, I don't opposite it, too. We have to understand difference with each other nation's culture. When we had a disscution about it in class, a student said "What is different between eating dog and eating pig?" It's all right.
Then, most of people will say, "The dog is a lovely pet." The pig will be also lovely pet to someone.
Therefore I think that It is difference of culture.
