"Unacceptable" is an unacceptable term to use in regards to the legal choices that people make. It is legal and acceptable for people to eat food which they have purchased and have had no hand in cultivating or killing. Perfectly legal. Perfectly acceptable. What is unacceptable is intolerance to other people's choices.
While humans may be omnivores, we also have very large brains, which helps dictate the choices we make. Some choose meat, some do not. Some choose meat that others kill, some do the killing themselves. Neither choice is right. Neither choice is wrong.
Supposedly my O Negative blood type makes me predisposed hereditarily to be a meat eater, but I often choose not to be. I like my veggies. There are supposedly other blood types that hereditarily (is that even a word?) predispose someone's body to thrive on food that is gathered, versus food that is hunted. It's only a theory, but sort of makes sense. Either way, both groups of people should not be stigmatized publicly for shopping at grocery stores versus growing/gathering/hunting their own food. Let alone not wringing their own chickens' necks.
Not to mention, this forum is called BACKYARD CHICKENS. My neighbor would call the cops if he saw blood running under his fence and headless chickens hanging from the fenceposts.
Let's just all get along and be a little more tolerant, okay folks?
