Is it acceptable to rail against gypsies or travellers? Negative stereotyping of those communities has become a popular (and populist) pastime this year. In this programme, we examine these and other stereotypes: why we use them; whether they tend to be true, and if they are, whether we should still shut up about them. Evan Davis takes a trip to the Appleby Horse Fair and asks some young members of the Gypsy and Traveller Community whether they feel unfairly stereotyped. Studio Guests: The economist, Sam Bowman and journalist Kate Bevan.
