In 2015, the poet-musician Grzegorz Kwiatkowski made a strange discovery at the site of the former Stutthof concentration camp in Poland — something he calls 'a carpet of abandoned shoes.' But these were more than shoes: they're both artifacts and symbols of the Holocaust — as well as a flashpoint of nationalist denialism and historical amnesia. *This episode originally aired on May 2, 2019.

Choose your country. It’s the first step towards finding the healthy variety of patriotic love. But what sort of ‘choice’ is it?
