The Achilles heel of democracy is non-violent demonstrations. Firstly, only the one who knows he is right will at all costs abstain from resorting to violence. Secondly, if democracy responds with violence it has proved the demonstrators point that the system is wrong. So democracy is in fact helpless against someone who does not resort to violence. This freedom of expression for individuals and groups within a given set of rules is of course also the strenght of the system since it removes the reason for resorting to violence. To ignore and not listen to a person will normally drive that person to resort to violence.
The medical profession being made up of individuals who would prefer dictatorship to democracy is of course using this fact when treating schizophrenics. The medical profession knows that all it needs to do is to provoke the schizophrenic to become violent and democracy will hand over absolute power to the medical profession allowing them to control and manipulate the system as they like. I don't know what is done to the schizophrenic at the time absolute power over him is given to the medical profession. My guess is that they use him to program society without their knowledge. This act of violence that the schizophrenic has commited can be used against him to break down his unconscious model for morality, probably the rest of the personality comes crashing down at this point.
From this we also understand that anyone who wants to undermine a groups message will infiltrate the movement and start violence during demonstrations and in this fashion invalidate the message of the movement.
As a consequence of this non-violence idea that is built in to democracy anyone who agrees to talk with democracy without intention of making any changes poses a threat against the system since another idea built into it is that both parties of a discussion are supposed to make concessions. This highlights North Koreas behaviour so far. However, if North Korea would agree to abandon the idea of nuclear weapons there should be a world of opportunities opening up.
Mohandas Gandhi is of course the person who initially identified this weakness in the democratic system.
