He's actually correct when he stated that people tend to believe what they read and/or see in the movies/books. He goes on to state that "entertainment is not value free. It has ideological content, it presents a world view that influences the people who watch the programming." Anyone who turns off the tv/radio for a week will notice how influential media can be. We're told how we should look and then run after that look. We're told what cars to drive and then take out loans to purchase that car. Much of the world considers this "normal", and we tend to justify it by telling ourselves that "It's just plain 'ol progress.", "I want to fit in." And our very ego's tentacles reach down into every thought.
I've never bought in to the idea that there's a "secret group" (The Illuminati, The Protocol of the Elders of Zion, etc...), but there absolutely is One being who has massive influence; The Prince of Darkness, The Father of Lies- Satan. He has been deceiving mankind from the beginning and, because of his deception and lies, we don't see things as they are and we placate ourselves. Many saints, both early and contemporary, tell us that our time is short here, the end is nearer than we think. But this message gets drowned out by all the commercials advertising things we need. By politicians telling us they're answer. By news media/networks deciding which stories we get to watch/read and how those stories will be edited. By pharmaceutical companies pushing their drugs by telling us, "You just shouldn't have to feel this way."
The speaker mentions "Information Control" a great deal. I'm not, nor was the speaker, referring to so-called 'conspiracy theories', but real information. Every day, news editors must choose which stories to print. Much of that decision is motivated by money because they need to sell their papers/publications. But there again, Satan tricks them and us into believing what we read/see/hear.
Although this is a frighteningly serious topic, Christians have known about this since the Resurrection. Those Christians who left their societies and went to the deserts have spoken at length about this "Information Control", though they didn't employ that phrase. The Fathers speak of Logismoi; assaultive thoughts that lead us away from Jesus the Christ. Jesus himself even warned us to be watchful, to learn discern truth from lies, to be "wise as serpents...". "Mind Control", although the stuff of great movies and literature, is very real. Satan works endlessly and tirelessly at getting at our thoughts and he will and does use anything to do it.
These days, we are bombarded by "information" from 24 hour news channels, the internet, etc... and the interesting/scary thing about it is how fast it travels these days.
As an Industrialized society, we tend to look askance at earlier cultures with their myriad of superstitions. But with all that "information" out there, Satan has made us really no better.
