Yes, it matters how people view you as we are a social animal and our very survival depends on the group. Stutters feel and are often ostrachized which is the very thing we fear most primally because it ensures death through an evolutionary lense. How people treat and given that it's everyone does affect our view of ourselves. We are literally being punched in a metaphorical sense in the vast majority of our interaction. Ancient peoples viewed stutterers as being possessed by demons or bad spirits. We were accused of witchcraft, were actually ostracized as children (left to die in the woods) and were barred in many cultures from having public roles. All these associations were negative as today. The demonic possension was replaced with mental health, especially anxiety assumptions, lack of intelligence, or that we have no idea what we are saying. A co-worker once asked if I stutter when I think, I guess its a valid question but intellectfully insulting nonetheless. It meant she viewed my thinking patterns taking as long at times for me to spit out a coherent sentence. The whole, "no one cares about your stuttering but you" and "its in your head" is just blatently wrong. People still stigmatize us and barr us from roles. We are the same animal. I always tried to make friends, connections, and be social. I forced myself to do social things that were challenging toward my stutter. In reality I wanted to do these social things it just became forcing myself through the ritual of humilation. I was forced to be an "introvert" by society simply by the fact I am forced to be isolated.
