Yeah, from your responses it seems you are invested in the industry. Maybe open your mind a little and consider other aspects of what is a complex issue. You do get Speech therapists that are wise enough to deal with the underlying issues that I mentioned but in my experience they are few and far between. As a stutterer it is something to keep in mind because it compounds the issue when you come out of a long and expensive speech therapy course only to quickly regress and have the weight of "failure" on your shoulders, nevermind critical family.
