Hate seems to be everywhere - whether it’s white supremacists marching on the streets of America, jihadists slaughtering Christians in Sri Lanka or the massacre of Muslims in New Zealand. In this five part series, BBC journalist Allan Little unpicks the mechanics of hatred and reveals how this dangerous emotion has been whipped up and disseminated throughout history. Allan Little begins with the hatred he witnessed on the killing fields of the Bosnian War, deconstructing how Serbian leaders like Slobodan Milosevic and Radovan Karadzic manipulated and weaponised history to inculcate a violent loathing that would lead to the massacre of thousands of Bosnian Muslims at Srebrenica. It's a hatred and an ideology that continues to inspire today's extreme far-right.
