I think this is a faulty assumption. You could be right, but I am far more willing to bet it is a symptom of the isolation and insanity of modern society. From reading the article, I got the real feeling that there was something in cannibalism that appeals deeply, in a psychological way to the nature of humans, as a way to bond and become one, spiritually with one another. Our society, has become soulless, and as a community, very spiritually unconnected to each other. I am willingly to likewise bet, that the apparent, "desire" to participate in cannibalism is probable higher in societies that are highly secular, cerebral, intellectual, atheistic, etc. and have been told the material third dimensional existence is all that there is of man's being. In America, the case is much different. The population has a much different view of it place in the cosmos. Although it's populations are spiritually used by the religious institutions for it's belief, it none the less doesn't hold with it's European counterparts. I think if the same add were run in America, the same amount of response would not be garnered. I could be wrong here. It is instructive that the book "Stranger in a Strange Land" was written by a scientist and a futurist, and therefor, in all probability, an atheist, also a communitarian. Have you read it? I recommend it for some insights into the psychology of this subject. In many ways it bears some resemblance to Richard Bach's "Illusions." But salvation is not found in the individual through uniting with the higher "consciousness", but is more of a communitarian principle, a bonding principle. The end result is the same. Where Bach present mankind's consciousness as part of a universal consciousness, Heinlein presents consciousness as part of a group consciousness, and to be "eaten" is to just physically rejoin what is in spirit, always a reality. It is holy and sacred. So, in the final analysis, when people in today's society are feeling "empty and alone" inside, spiritually, after our highly atheistic and impersonal society has told them there is no such thing as god or any other dimensional consciousness, is it any wonder they think. . . hmmm, maybe I should eat or be eaten?
