We all know the psychology of witch hunt. Three factors are needed: the ones who are different and behave differently than the majority; the majority who unite themselves in cruelty and stupidity; and the ones who are clever enough to manipulate the majority, and use the "witches" as the target of hate of the majority, and thereby strengthen their own power.---- And we can find always thousands of reasons to hate each other, to fight each other, and to kill each other. I think, the history of the humanity is about the inhumanity. We have a passion for cruelty. I would use the bonfire/stake installation as a symbol of cruelty and stupidity of the human nature.
