Some animals are more equal than others.
That only applies to humans as far as I am concerned. And it is strictly cultural. I despise cannibals and if we have some weirdo in America like Dalhmer who is killing and eating people, that person has obviously got to be stopped.
However, if we are talking about a tribe in the jungle or on an island in the South Pacific that makes it a habit of eating their enemies (and any strangers they catch), don’t go on vacation on their turf.
