I argue that we cannot just lock up extremists and throw away the key - if we do not understand what turned them extreme and manage to argue on their level, which in case of religious fanatics is understanding and talking about the nature of The Divine, a dialogue might become impossible. The main reason why e.g. I personally was afraid to seek professional help after leaving a cult was that I feared  I would be told that believing in The Divine and feeling energies is pathological in the first place....Understanding the psychology of radicalization and brain washing could also help us to prevent kids (and adults) being 'turned' awry in future....
