David Icke isn't so much crazy as he is reporting on the kind of reality that the current situation has forced him to see. I have personally met a lot of people who I cannot believe are quite human. Mentally they definitely are not a form of life that I can see as natural. This may come from their own fiction that they have kept in their own families, inspired by the Malleus Maleficarum and similar works, using the texts that are supposed to warn us as templates for the way that they treat other human beings. The demonic definitely exists in human minds. All that it has to be is a compelling fiction that becomes a way of life. They dress up and draw pictures to keep their programs within parameters, as fetishes, for their minds to focus on.
I can't prove it. I can only assume that physical manifestations are illusions. If they are, what brings on those illusions? Making people believe that they see something that isn't there is part of the method. Some of these people may be able to project images with their minds strongly enough for them to be seen by others who are sensitive. Sometimes doors to perceptions like that open for a short time then close again. The people who receive those perceptions often find that they never, ever want to see them again. More likely, simply because it's a lot easier and requires nothing special, the people who want to gaslight someone use tricks of light and shadow, a little bit of costuming here and there, a touch of makeup, and some psychological tricks. Hell, why do truckers perceive underage prostitutes as lizards? It's because their minds are cold, their bodies are cold, they wear reptilian colors and adornments, and they have just a little bit of a capacity to wrench someone's perceptions around. People like that give me more of a motivation than almost anything else to seek real reality and stay away from perversions. I am vulnerable and anything like that that gets its claws into me makes me physically ill. I only fuck within my own phylum for a very good reason. There's a reason why even truckdrivers aren't such great customers for those services. A man can't really feel like they're just in it for the money.
If it is all bluff, if it is all just smoke and mirrors, it is still just as dangerous if not more. Modern methods let them hide in plain sight because it is provable using science that there is no such thing as reptilians. Then those whose hearts and minds tell them that they are dealing with the demonic, since it has been proven that there is no such thing, no alien DNA involved, no strange magic, no Atlantean technology, why they must be crazy. The myths work really well to hide the fact that there are people who are born psychopaths, will die psychopaths, and will badly damage society while they are alive, and that they are in power. At the same time we are stuck with them because they are like a language and a body of knowledge that, if decoded correctly, tell us the truth. Without them we might not have a clue. Either that, or we would be a lot better at getting bastards out of power. One day I feel one way, the next the other.
