I've formed my opinions through my own personal experience as a stutterer & from my interactions with others who stutter. Obviously your experience has been different from mine as you've met people who are on the more severe end of the spectrum, so the term disability may very well apply. I understand your point of view & can agree that there are most definitely individuals that could be considered disabled, I just feel that those cases are few & far between. I feel like defaulting to the idea that everyone who has a stutter is disabled would be doing a dis-service to ourselves. Everyone I've ever met (only about 10 people or so; not everyone in the world ever) who has stuttered all had some kind of breathing techniques, tricks they learned in speech therapy, or something that has levied some degree of control over how severely they stuttered. I feel like automatically defining ourselves as disabled infers a total lack of control over this problem that we have, when in reality I feel that most of us have more control over it than we think.
