Brilliant subject!

As to Down syndrome - I would have any unborn child of mine diagnosed with it aborted. At the expense of never having a nights' peaceful sleep anymore for the rest of my life.

Deafs. My initial reaction too was that not curing it to keep deaf culture intact is daft. Thinking about it a bit more, I'm not so sure anymore. I cannot simply dissmiss the counter arguments.
There are so many angles to it. Food for thought...
