As it says
on a wall somewhere in Sheffield
"Meat is murder."
"Eat more meat."
You see, eating meat might not be the best thing for the human race, the planet or your own sense of morality, but if other animals wanted to have a say they should have spent more time evolving into something intelligent and less time learning how to eat grass.
If they are not willing to contribute in any other way then they deserve everything they get.
