Dean 'is' a good bloke and just says what he thinks.. He may come across a bit cocky and rude to some that don't know him but sometimes just words alone can do that.
Dean is a classic for thinking outside the square.. I knew George Greenough once and he reminds me so much of him.
I'm sure Dean just wants to stir the pot and get people thinking more rather than just following.. and he feels strongly about what works best.. IHO..
