The Bolshevik revolutionaries got power by infiltrating secret societies–mostly the powerful masonic lodges. They formed secret [bad] societies within secret [good] societies. To hide in plain sight & gain power/influence over the [good] society.
It's like those wooden russian dolls, the outer doll is the good society/church and as you go inward it gets more and more twisted until you have a small group of satanic cults in the center. This cabal of bankers/industrialists families communicate with demons they believe are trapped in the earth, and grant them power/knowledge.
It's really not "The Jews" or "The Caltholics" or "The Masons" etc. It is the secret societies within those groups–hidden in plain sight.
