I do not label Downs a "severe" disability from a position of ignorance. I know one Downs man well, and have met plenty of others -- including a lovely 12yo girl who could ski and read. but she was very "high" Downs.
The article had to be unbalanced in the sense that you all describe; to put in positive Downs syndrome accounts in the same story would have been highly insensitive; almost gross.
The Downs man I know well is about 19yo, and my cousin ( "M." ). I'm fond of M., and I don't wish him away, but I would have fully supported his mother if she had chosen to terminate him as a fetus. He is considered "high" Downs intellectually, but low Downs physically, which suggests that his ability to become a "functional" and independent member of society is probably about average for Downs people. He cannot read, or (properly) wipe his own bottom after going to the Lav. His mother & older sister do much of his physical care, including cleaning, bathing & cooking. Like most Downs adults I've met, he is extremely shy, to the point it is difficult to engage him in conversation. He had to have major surgery around 10-12 yrs old twice, because it failed the first time on skull bones that failed to fuse together naturally (related to his chromosone defects). The family went out rarely for years because of the awkward (and to M., embarrassing) contraption he had to wear on his head. He is mostly wheel-chair bound, as he struggles to walk more than 100 yards due to poor muscle tone & weak knee joints. He has no heart defects, unlike 30-40% of Downs people. He has had a weight problem, but probably lacks thyroid disease (unlike 30% of Downs people). He lacks many social skills, although a proper "training" course could fix that. His mother is deeply worried that like most Downs people, he will develop an Alzeimher's type condition before age 40. Although his mother has blossomed a lot with the duty of care for him, some of the rest of the family have been adversely affected. His aunt, who knows & loves M. dearly, tells me she almost certainly would have terminated if she found herself with a Downs baby. M. seems quite similar to the young Downs syndrome man who lives across the road, who is about age 30. His parents are elderly, and I worry about their son's care when they become too frail. Luckily, M.'s mother is still quite young.
A friend has a baby with a rare chromosone defect. The child has problems similar to Downs. Lovely girl & I often think 'Could I "terminate" her?' But when I see how stressed out her mother is with her condition & problems that come up, the choice seems easier.
I would prefer to not have a baby for life; having Downs syndrome is a lot like being a baby for life. That to me is severe disability. I won't argue the rest of the points because I can see they are well-covered in "the other thread".
