Not all Down Syndrome patients are retarded. I went to college with a victim of Down Syndrome who was certainly not retarded.
I have lived in the same suburb of Seattle for 33 years. In our neighborhood there lives a DS man with his elderly mother. I have no idea how old he is; although, I think I heard someone say he was in his mid or late 40's. He has worked at the grocery store that I shop at for many, many years. I see him out in the yard with his mother helping her do gardening. He reads the newspaper, loves sports, is always at his job and has been doing these things for years. He has a life, just like the rest of us.
Just because he has Downs Syndrome, what makes him less human than the non-DS people employed by this grocery store?
