This week:

Are Roma people unfairly stigmatised?

The case of a young girl found with a Roma couple in Greece to whom she is not related has raised fears of a backlash against a community that already feels it is unfairly stigmatised. Within days of the Greek revelations, two children from Roma families in Ireland were removed from their homes by police, to be returned after it became clear they did belong to their parents. The families involved have demanded explanations and a Roma organisation in Ireland has said the actions of the authorities could 'fuel racism'. So are Roma people unfairly stigmatised?

Is time to pay for NHS treatment?

The NHS has been under the spotlight this week. A regulatory body described a quarter of hospitals trusts as being in danger of providing poor care. And the Government says £500 million could be recovered from foreign visitors and short-term migrants receiving health care. Rock star Roger Daltrey has questioned the effectiveness of the NHS, claiming it encourages people to lead unhealthy lives because they know they will get free treatment. So is it time to pay for some NHS treatment?

Do stay-at-home mums deserve more respect?

A child development expert says full-time mothers are now subjected to 'motherism' - a prejudice against women who choose to stay at home full-time with their children, rather than combining that with paid work. Dr Aric Sigman said that if such attitudes were directed at people due to race or sexual orientation gender there would be a huge backlash. Sunday Morning Live debates whether stay-at-home mums deserve more respect.

Is it possible to have a 'church' without religion? The Sunday Assembly believes it is. The atheist organisation stages gatherings, which it says extract the good things out of religion without making belief in God part of the package. Sunday morning Live attends one of the 'services' and also discovers a Church of England vicar, who says he doesn't believe God exists either. Show less
