"Eighty per cent of our newspapers are anti-PC. There is no area that is not up for discussion. I do not believe that people go around on their tiptoes afraid to offend women or ethnic minorities. But we have become worse at the exchange of ideas. We are not good any more at having really honest debates without upsetting people. We have become very good at abusive, hysterical exchanges and less good at intelligent debate. We do need to develop a healthy trade in ideas."
