Two years ago, audio producer Lewis Raven Wallace was fired from his job at a radio programme made by American Public Media.

He'd refused to take down a blogpost he had written in response to Donald Trump's recent inauguration. As a member of a marginalised group - Lewis is trans - he delves into the myth of 'journalistic objectivity'.

Lewis has since gone freelance, and is about to publish his first a book. It will be accompanied by his new podcast - both called The View From Somewhere.
