When a significant portion of society collectively rejects reality, what happens? I'm speaking of the famed "mass formation psychosis" that seems to have gripped the masses. Plenty of people see it--in fact, most of the people I talk to agree that something strange is going on.
Any honest evaluation of humanity must acknowledge the fact that people are crazy. Not just a few people. Not just some people. A lot of people are crazy, and if we're honest with ourselves, we must admit we are probably all a little crazy from time to time. After all, going crazy is glorified in music and pop culture. It's seen as an escape from inhibition. It's acceptable to cut-loose, let-down, and just be a human from time to time. But this is different.
If acting a little crazy is normal behavior, there still has to be a line somewhere that indicates when a person is a little too crazy, like off-their-rocker crazy, lock them up crazy, or just good old fashioned bat-shit crazy. I suggest that this kind of crazy, the bad kind of crazy, the we should be concerned kind of crazy, the dangerous kind of crazy, has a distinguishing behavioral trait. People who are this kind of crazy reject reality in exchange for their own delusions.
While we all get a little crazy sometimes, we ultimately come back to reality and engage life in a somewhat "normal" fashion. But the real crazies, they never make it back. Sometimes it's drugs, sometimes it's mental collapse, and sometimes people are just born that way--but sometimes, sometimes, it's due to emotional assault, covert conditioning, and psychological warfare.
