The people who eat dogs, and rats, and cats and snakes and monkeys and all sorts of things we don't started doing that centuries ago because that was the meat available to them.  

For millions of people worldwide, that is still just the way it is.  They get their protein however they can. 

There is a reason so much Asian food emphasizes vegetables, stir-fried or otherwise; poor people can't afford meat.   

When I ate it in South Korea, all I knew is that it was deep fat fried Yaki Mandu.  Excellent!  

For one MRE, you got an order of Yaki Mandu, a Moon Pie and an ice cold Pepsi.  Cooked on the spot!

Unless you are vegan or vegetarian, the difference here and there is that here you don't get to pet the calf before it is butchered so that you and I can have veal scaloppini.  Or veal parmesan.  We don't see an animal die so we ignore that fact.  

We are just effete.   Or we have unintegrated values.
