There are tens or hundreds of thousands of rebellious young people in North America who briefly dabble in a form of Satanism. Their source material is often in the books by LaVey, perhaps supplemented by writings about Gothic Satanism by Evangelical or Fundamentalist Christian authors. Sometimes, they will also include elements from books on ceremonial Magick, Wicca or other Neo-pagan religions in their practices.
These dabblers are responsible for Satanic graffiti, and (rarely) animal sacrifices. Some look upon Satanism as a method of rebelling against their parents' beliefs. Fortunately, it is usually a passing fad that they quickly outgrow. Satanic Dabblers have no connection with Religious Satanists. There is of course no connection between the teens and Gothic Satanists, because the latter do not exist.
