The first time I really read anything about the Diagnostic and Statistical Manual of Mental Disorders(DSM) was reading a book called “A Dose of Sanity” by the late Sydney Walker, Jr.  He was a psychiatrist that was completely disgusted with the laziness of doctors and psychiatrists and the abuse of the pharmaceutical industry.  He gave examples where he found brain tumors where the person was recommended mood altering drugs because the medical practitioner would not take the time to diagnose properly.  

And now it just keeps getting worse with the latest edition of witchcraft and wizards potions: DSM-V

This from Wikipedia:

“Oppositional defiant disorder (ODD) is a childhood disorder described by the Diagnostic and Statistical Manual of Mental Disorders (DSM) as an ongoing pattern of anger-guided disobedience, hostility, and defiant behavior toward authority figures which goes beyond the bounds of normal childhood behavior. Children suffering from this disorder may appear very stubborn and often angry.”

This is a bit frightening.  Someone mistreating a child just has to send for the drugs to keep them from fighting back. 

This is a decent article on “oppositional defiant disorder”:
The Mind Unleashed

Many people that are unable to confront the evil that does exist in this world will not believe this will be used by politicians to control populations.  But history proves that it will time and again.  I believe that people are mostly good and because of this they tend to hope or believe that nothing will get that bad.  Just remember the ‘frog in the pan’.
