To denigrate the work of someone who has such success because you don't agree with it, is both unkind and unprofessional, and only contributes to the tension in the stuttering community at large.(a) I denigrate his statements on the causes of stuttering, because he does not change them in the face of obvious and clear evidence to the contrary.
(b) I do not denigrate his desire to help and do not say that he has not helped some people.
(c) not "I" don't agree, but a lot of scientific articles and researchers don't agree with him.
(d) What is professional? To stay silent on the scientific non-sense he is propagating?
(e) What you can call "tension" is what I call an open intellectual debate with the demand for consistency with established science.
His views are religious. He and his followers want to believe, and arrange their world view around. Why does Bodenhamer not change his views despite clear empirical and theoretical arguments? Because he has the mind set of a believer of an unenlightened type. Maybe we should also ask Bob Bodenhamer whether he believes the earth was created a few thousand years ago? Does he deny evolution? Does he believe in a personal God that actively intervenes in our life and is not just a creator?
Given his state of mind on stuttering, I would not be surprised if he ignores empirical evidence here, too.
