What to call Islamic State, Greece, #WhoIsBurningBlackChurches

Does it matter what media and politicians around the world call Islamic State? British Prime Minister David Cameron has asked the BBC to stop calling the group Islamic State. Are the media in a propaganda war in which words and perceptions influence events?

Also, we hear Greeks on both sides of the austerity and Eurozone referendum debate. Plus, #WhoIsBurningBlackChurches is trending after a series of fires at African-American churches across the US South. Six fires in the past week in Florida, Georgia, north and south Carolina and Tennessee. We hear from people there.
