Yea thats true, it's not always nervousness. How you respond to these people can either benefit of hurt your speech as well. If you allow other people's reactions to negatively impact you, you will always be the leaf in the wind. So as hard as this pill is to swallow.. Real transformative work happens when you can start empathizing with them. Seeing it from their perspective. Seeing how they are also just doing their best. But yes I understand it can be frustrating at times. I'm only saying this because a major turning point for me was when I felt a true sense of belonging in social situations, at work, school etc. When I would feel like I would truly belong, my stutter would fade and my true character would come out. And when we are in a place of separation saying "these people don't get me" "they don't understand" that mindset ultimately holds us back from feeling safe to be ourselves. Which will cause more stuttering and more negative emotion.
