Renowed atheist Richard Dawkins has stated that it would be immoral to bring babies with Down syndrome into the world if you have the choice.

The philosopher has managed to go one step further than his controversial comments on ‘date rape versus stranger rape’ to voice his opinions on what it would be ethical for a mother who is informed that her unborn child has Down Syndrome to do.

He started off his conversation with followers ethically enough, highlighting the plight of women in Ireland, where abortion is illegal, in light of the recent reports of the country’s refusal to provide a safe abortion to a suicidal rape victim. She was forced to give birth.

“Ireland is a civilised country except in this 1 area,” he tweeted, adding “You'd think the Roman Church would have lost all influence,” to caption a link to a similar article.

But after engaging in conversation with a number of users, his ethical values appeared to come a little unstuck.

“994 human beings with Down's Syndrome deliberately killed before birth in England and Wales in 2012. Is that civilised?” @AidanMcCourt asked.

“Yes, it is very civilised. These are fetuses, diagnosed before they have human feelings,” Dawkins responded.

“I honestly don't know what I would do if I were pregnant with a kid with Down Syndrome. Real ethical dilemma,” @InYourFaceNYer chimed in.

“Abort it and try again. It would be immoral to bring it into the world if you have the choice,” he tweeted back.

Naturally, his reasoning prompted a slew of further comments – and subsequent commentary:
