Certainly. I never said that my preference for one explanation implies that I would deny objective data. Intellectually, I am fully committed to the truth. At the same time, this hypothesis is not proved beyond doubt as far as I understand. Also, I was wondering if you are a person who stutters? Because, laying aside all the scientific aspects of it, stuttering is a very emotional experience for those who go through it. And yes, the explanations for Stuttering does certainly have personal and emotional connotations for those who stutter. This is because one of the most frustrating and painful aspects of stuttering, is the fact that most people tend to explain away stuttering as being caused by childhood trauma, a lack of confidence, insecurity, a bad habit etc. So you see, the explanation that Stuttering has a neurological cause was very helpful in countering these claims, while the possibility that it's neurological nature is a consequence rather than a cause, reinforces these beliefs which are rampant in society- beliefs which are damaging to the person who stutters because they make out Stuttering to be a flaw or an emotional issue, rather than a disorder or disability in the eyes of other ppl (even if it's really not). Even my parents (who are doctors) believe that my stutter can be traced back to an incident when I was 1 yr old in which my mother left me alone in the care of my grandparents (I was strongly attached to her and had never been parted from her before). She claims I began Stuttering as soon as she saw me next. Read this extract from John Hendrickson's 'Life On Delay: Making Peace With a Stutter'- "I felt relief in discovering that stuttering was wrapped up in the complex, plastic development of our brains. I was reassured to hear that, although stuttering may be subject to psychological influences, it was a complex, biological condition. At the base of it, it was a relief to know that stuttering was not my fault, that it was not my parent’s fault, or anyone else’s. I had simply been born with a neuroanatomical weakness, nature had not chosen to give me effortless speech." This is my perspective, I realise people could see things differently.
