If you are an evolutionist atheist, eating anything that was living is a form of cannibalism. You believe that descendants of animals and even plants could be people someday. To avoid becoming a cannibal, you should adhere to a strict diet of milk and cheese, and make sure there are no signs of living organisms in either. Hmm... On second thought... atheists shouldn’t think cannibalism is wrong, because to them, right and wrong don’t exist.

Side note: Society accepts and embraces eating meat, so can somebody tell us why so many atheists are vegetarians because they think eating meat is wrong? What makes it wrong?
