This week, we are re-airing Sophia's conversation with Dr. Melina Abdullah from 2019. Dr. Abdullah is an expert on race, gender, class and social movements. She was part of the original group of organizers who formed Black Lives Matter and she is a professor and Chair of Pan African Studies at California State University, Los Angeles. She joined Sophia on "Work in Progress" to talk about the moment the Black Lives Matter movement came together, white privilege, how and where these systems originated, how we can speak up, and more.
