Excellent post v4vapid. This past summer I read Dan Brown's Lost Symbol which deals with much of this same subject matter. Sadly, the book was a let down as it gives the Freemasons a completely free pass for their nefarious activities and mocks those who question their actions and motives. The following link may also help people expand their awareness on this interesting and controversial subject.
Secrets Hiding in Plain Sight - Quite possibly the most in-depth video online revealing esoteric symbolism used by the elite and incorporated into society. https://www.youtube.com/watch? v=L777RhL_Fz4
