Since we are all hypnotising ourselves and each other most of the time, it makes sense to get some awareness and begin hypnotising ourselves and each other positively. Professionals have no greater moral (or practical) claim on hypnosis than any other body of people. I salute the work of bringing hypnosis to the masses.
PS: Many years ago I had the privilege of suffering the ministrations of a registered hypnotherapist who helped me prepare for childbirth with the frequently-repeated suggestion that I would feel NO PAIN. Can you guess the consequence? Licensing, registration, and a "broad professional background" are, in themselves, fairly unhelpful.
