Why would you expect Richard Dawkins to be against abortion?
If you were to ask somebody with Down's syndrome whether they would prefer the life they were given or would prefer never to have been born at all, what sort of response do you think you would get? You don't have to appeal to religion at all to establish why Dawkin's position is morally abhorrent. All you need is revealed preferences. That same argument applies to eugenics in general.
He seems to feel it is immoral to bring someone into the world to suffer. It does seem a bit selfish. A genetic disease (I forget the name) runs in my family. The men have a gene mutation that causes severe cognitive development issues for females. My cousin was born with it. Her parents now have
a 50ish year old daughter who could never take care of herself, has never had a boyfriend, can't drive, didn't go to school, has all kind of physical issues and still wears diapers. She couldn't answer your question because she has no ability to understand the implications. But does that sound like a high quality of life? Her parents didn't have any tests done even though they knew the possibilities. Who knows what she thinks locked in her mind that she can't express. She may not be as eager for this life as some assume.
And I know this. Had my wife gotten pregnant and we got to the point where the test could be done if we found the fetus was a female and was going to be severely challenged as my cousin is we would have aborted. We agreed on that from the start. I am not about to bring someone into this world to suffer their whole lives.
