These accusations that (mostly female) entertainers are part of a Satanic cult out to corrupt our impressionable youth is nothing more than a modern variation of the witch hunts, just like the Satanic Panic of the 80's and 90's. A great example for anyone who thinks that humanity has become far too rational and enlightened to fall into the traps of superstitious thinking like our ancestors did.
Of course the government and new world order proponents aren't beyond using whatever means they can to control and influence the public, but this whole illuminati symbolism hunt/listening to songs backwards/overanalysing trite lyrics nonsense is laughable. It's obvious these musicians are deliberately playing on this shit--it's a great publicity gimmick for 'artists' who only rely on gimmicks in the first place, and don't forget how dark and edgy it makes the Disney kids who desperately want us to view them as grown up. There is nothing remotely new about this either; there was a fascination with esotericism/mysticism in Hollywood as far back as the silent era and dabbling in occultism became really trendy in the 60's (Anton LaVey even became something of a celebrity because of it).
It makes me glad Lana isn't more famous because there are plenty of potential 'Illuminati clues' people would love to read into if they knew more about her. Like the Daily Mail interview where she said she wished she was dead and that she doesn't want to keep performing but she has to.
