Alllllrighty then . . . no one wanted to touch this topic!
There are many cultures (I am unfamiliar with the Tongan's) in our big world. Some eat all animals, some eat none.
I would never even consider living in a culture where people could just bbq up Rover on Sunday afternnon.
BUT consider this: in CIVILIZED cultures (USA and others) animals are treated horribly their whole lives and then slaughtered in inhumane ways (you can see videos online if you don't believe me). . . all so the meat industry makes its money. ugh!
Over the years I have become almost a complete vegetarian---on rare occasions I eat fish or organic meats. At least when I consume organic meats I know that the animals were not treated unkindly just to fill someones belly! More & more I don't even want to eat meat at all---you kinda lose the liking of the taste.
So, hope this wasn't considered off topic. Its just what came up for me.
