Let's use your same reasoning but instead of stuttering, lets say we're talking about seizures. Why isn't the focus on the observer effect when a person has a seizure? Is it the interpretation of the person witnessing someone having a seizure that needs to be changed? Absolutely not. Seizures have detrimental consequences to the person experiencing it. Stuttering is no different. Denying this reality to people who stutter is a disservice. The experience of someone with a mild stutter is worlds apart from the experience of a severe stutterer. Even someone with a mild stutter can experience a block that can be traumatizing for the person. All this talk about "observer effect" or "stuttering is a variation of normal speech", as others like to claim and as you insinuated, alienates the very people they're supposedly advocating for. I get that this post is coming from a well intentioned place, but impact matters more than intention.
