I don't mean to offend any Chinese people, but I have to laugh. It seems like they will try to eat anything that isn't nailed down.
( Yes waiter, I believe I'll have the Tiger noodle and a side of monkey brains. My wife will have the Cocker Spanial with a side of poison fish. And, oh yes, bring a pitcher of mother's milk for the table.)
But I don't see any morale or ethical problem with consuming mother's milk unless it deprives an infant.
I once watched two Chinese kids, 8 or 9 years old eat lobster. They each had their own lobster. When they were done with those things, there was nothing left. They ate the gills, the tomally, and every other organ in them, including the eyeballs. There was only a pile of shell left on the plate.
Made me feel wasteful...
