Everything you said is right, I love the way you put that. It sounds a lot like if I were talking to Jordan Peterson haha. With that said, so much of what you said is right when it comes from an already negative outlook on stuttering. Appearing indecisive or appearing like you're lacking confidence is not mandatory. If you have a negative outlook on stuttering and it arises shame, embarrassment, inferiority, and it causes you to tense up everytime you feel a block coming on. Then of course people will pick up on that. But when's there's a healthier relationship with stuttering, and it doesn't arise those emotions (doesn't for me 99% of the time now) then it won't impact the conversation in the slightest most times.. You can only be "pigeoned holed" as you say it (I think that's a dope phrase) if you feel secluded from the group. That feeling of seclusion or feeling like you don't belong comes from a place of feeling unsafe to express yourself authentically. I truly believe (this is what I've done) that once you have the ability to feel completely safe (meaning, the deep down knowing that even if you stutter you will still be fine) in situations, you will never feel secluded, you will never feel like the odd man out, bc your self worth isn't tied to things outside of your control, aka peoples judgements.
