I'm interested to hear what you disagree with about the theory. Experiences of stuttering vary a lot from person to person, so maybe this explanation causes some people's stuttering, but not yours. The author does describe himself as a lifelong stutterer who has struggled with it for a long time ([here](http://www.stuttering-theory.eu/author.html)'s his biography). He even says that this theory partly derives from ways that he's been able to address his stuttering.
