Anton LaVey, founder of the Church of Satan, directly lifted passages from the 19th century proto-fascist book "Might Is Right" by “Ragnar Redbeard” (Arthur Desmond) and did so extensively and without credit to produce a substantial part of LaVey’s most famous and popular work "The Satanic Bible".
This has been known for a very long while, although most Satanists tend not to be aware of just how shamelessly and thoroughly this work was done.
This article demonstrates exactly that.
