I worked in a nursing home around 2010 and I recall one patient who was probably in her late 70s, she had a stutter. She told me she grew up in the rural Midwest. Because of her stutter, she was considered to be stupid and was not allowed to attend school. She figured out a way to educate herself and ended up becoming a nurse with a long successful career. She was a tough person and had a lot to say about all the terrible assumptions that she refused to let hold her back.  Historically, people with disabilities and evident differences have not been treated well.
