Between June and July 2018, Layla Saad ran a 28-day Instagram challenge under the hashtag `MeAndWhiteSupremacy, for people with white privilege to unflinchingly examine the ways that they are complicit in upholding the oppressive system of white supremacy. The challenge quickly went viral, with thousands of people from all over the world diving deep for 28 consecutive days to examine and take responsibility for the ways in which they uphold white supremacy. The challenge catalysed a worldwide awakening for thousands of white-privileged people to begin to take ownership of their personal anti-racism work. This updated and expanded book takes the work deeper by adding more historical and cultural contexts, sharing moving stories and anecdotes, and including expanded definitions, examples, and and further resources.
