Choosing not to abort a deaf baby is completely different to aborting a hearing child because they want a deaf child. The latter is totally inexcusable.
As I said I can understand wanting to only bring a child into a similar environment to fit in but I don't agree with it
I post as a former foster parent, I suppose classed as typical middle class in the great scheme of things, and it was difficult for children from a different backgound to easily fit in and live to our standards
