What isolated little hubs might debate amongst themselves does not really very much impact the world at large. Satanism isn't really growing at the rate it is because of LaVey...it's actually growing in spite of him. It is a global response to a more global sense of what this term really means and neither LaVey nor Webb have their fingers on this pulse at all but are simply dealing within the confines of their own narrow, self-serving definitions. In the final analysis, nobody really cares. Satanism goes on quite well enough with or without them. It is defining and redefining itself constantly. Satanism is ultimately a much broader context than Setianism simply because there is no reliable *character* called Satan...you can't substantiate it...it never happened...no one even really knows what it is supposed to look like! It was all a fabrication...yet the power underscoring this term lives on. Satan is an idea and a force underscoring an idea.
To a Satanist Set is just one of many of Satan's faces. To a Setian Set and Satan are mostly irreconcileable. The difference has nothing to do with Satan's association to "rebellion". Setians have elected to lock into a character called Set...Satanists have elected not to. You can debate these things until you're blue in the face but in the meantime Satanism will continue to be mutating in leaps and bounds. Because it is not locked into any pre-established patterns it can go anywhere it needs to.
