Yea, I think it's hard for non-stutterers to grasp or wrap their heads around the concept of not being able say words on command and also why we're not able to articulate them. They will immediately assume it's due to some psychological reason because that's relatable to them and that's what non-stutterers experience sometimes. I find that I have to specify that I'm really not able to say certain sounds, like vowels or consonants, and it's only then that they kinda get it. Because a non-stutterer has never had that problem, not being to say the most basic of sounds of their language. There's also the fact that there's generally very low public awareness about stuttering. And really most other communication disorders are not well known like aphasia, apraxia and dysphasia. Mostly due to their extremely low prevalence in adulthood and they fact that you often can't communicate to other people and explain to them the condition. It's kinda a catch 22 situation. News and information spread best via word of mouth, especially before the 20th century before the internet and social media was a thing. It'll take a while if ever for awareness about communication disorders to catch up and be more known if ever.
