Hi Harry!
I guess you have a point and you certainly have a right to voice it, but you do get a lot of Paraliminals in the course and you can return it if you find fault with it. So what's wrong with giving people a little encouragement to give something a try that might change their life? If the advertising were played down, then wouldn't people say, or feel "That can't be much of a course if they are not bothering even to advertise it properly, can it?". Just a thought.
