We should just treat it as a mentally illness and not expect much

So when a carnist comes to a vegan page or a post that calls for humanity and shows how animals feel pain too they have to jump out and share a picture of a steak or something and go like "mmmmm meat" as if to make vegans angry while we all know meat screws the body up. This behavior is the equivalent of: look how I'm hurting myself, look and despair ha ha ha. Dfk?
