The Times article describes people with Down syndrome advocating against the diagnostic test. This is similar to deaf persons arguing against the use of acoustic nerve prostheses. Whatever social noises we may make, abortion is a pretty clear statement of honest perception.

Remember, it won't stop with Down syndrome. We will have our eugenics movement, for better and for worse.
