Conviction doesn't make them true. This guy is brilliant - he is one of the foremost practicioners of NLP. It is the ability to use Neuro-Linguistic Persuasion on people to get them to do and admit things out of their control using the power of their own subconcious against themselves. It you have a chance to see him in action (dvd, his own show, books) you would be astounded at what he can make people believe. This is why religion is an effective enslavement of the mind.
