I doubt Rand was an actual Satanist although some may have moved in her circles. They may take quotes to fit their own teachings, but the fringes of the Left & Right always find what fulfills their needs and ignores the other aspects of a doctrine and revises it --the economics, the freedom from taxation, Capitalism.. etc.
I wonder if she always took herself as Gospel as much as others chose to do--she has said on subjects she didn't always know all the facts.
It difficult finding the answers to Life.
