Extinction Rebellion co-founder Roger Hallam joins me to discuss the organisational model of XR. We also chatted about the booklet Roger has written on the strategy of XR - 'Common Sense for the 21st Century: Only Nonviolent Rebellion Can Now Stop Climate Breakdown and Social Collapse'. And finally we also discussed the criticism XR has come in for regarding its tactics of mass arrest and a perceived failure to properly engage with people and communities of colour.
