100% agreed. If the societal expectations weren't there, the only negative feelings associated with stuttering would be because of the physical sensation of not being able to get your words out. The vast majority of the negative impact definitely exists solely within and because of the societal structures of what is considered to be "normal" and "abnormal" (meant not in a derogatory but in a purely sociological, analytical way). Any person who defies those expectancies of normality will be confronted with their abnormality by our society. This is of course not limited to people who stutter as it includes any person with an attribute that is considered to be "abnormal". To bring it back to stuttering more specifically, I can definitely relate to the stigma of stuttering being the driving factor. A huge part of stuttering is related to (social) anxiety which wouldn't exist apart from society.
