Dawkins became embroiled in Twitter row, when responding to another user who said she would be faced with "a real ethical dilemma" if she became pregnant and learned that the baby would be born with Down Syndrome.
Dawkins tweeted in response: "Abort it and try again. It would be immoral to bring it into the world if you have the choice." A strange sense of morality indeed!
