Instead, a bunch of bored aristocrats like Alister Crowley thought it sounded like a great excuse to have orgies, so they slapped a label and brand name on it and wrote the rules. LaVey adopted some of the ideas into Satanism when that became the new "in" thing for the rich and bored. Mix those two together, filter it though a generation or two of people like Silver Ravenwolf, and voila. You have modern Wiccans.
The embarrassment of being associated with people like that is why the more serious practitioners keep it a secret. Non-pagans aren't the only people laughing at the hippie wiccans.
