A few researchers out there like Jordan Maxwell cover some of the symbolism. Other researchers like David Icke take a more varied route with the whole reptilian thing. And Michael Tsarion... well... he has a great imagination.
But one thing is for certain. The elite of this planet love symbolism. They get off on it somehow. It's everywhere. It's all esoteric/exoteric, meaning some symbol is a representative of one concept to some people, and means something entirely different (mostly literal) to others.
The question is, what does it all mean? I don't profess to know, but I wish I knew more. Right now it's mostly speculation and hypotheses.
One thing's for sure... those in power are....eccentric. That's the most polite word I could choose at this time. Otherwise, I have more colorful descriptions. lol
The series of books called Tales of the City, written by a homosexual from San Francisco, features snippets of information about Bohemian Grove. One of the characters attends it and meets a homosexual prostitute there, from memory.
Tales of the City, which is very much focused on homosexuals and bisexuals, was ripped off wholesale to create the overtly heterosexual Sex in the City.
