Excellent article as it proves that if you want to 'knock' someones opinion, view or ideas all you have to do is bring their 'charactar', mental ability or mental health into question.
That way you get to say, 'well he would think like that, wouldn't he. There must be something wrong with his head!'
I believe this kind of tactic is used against the '9 - 11' conspiracy theorist, the Global Warming doubters and those who believe there was more to the death of JFK than meets the eye. Even Hitler and Stalin used the 'mental health' card against those who doubted their policies.
Governments and their lackys do not like to be questioned and so everyone who questions them is bad in one way or another and they can pay any psychologist in the world to say so......with YOUR money!
Hows that for a conspiracy theory??
