Contemporary protests movements, which are distinguished from historic movements by relying on decentralized leadership and utilizing social media and technology, have a central role in addressing social justice issues. Black Lives Matter represents one of the most influential and controversial of the contemporary protests movements. Much of the controversy is connected to misunderstanding, distorted portrayals, and attempts to discredit the movement. Through an examination of the history of Black Lives Matter, and consideration of issues such as privilege and polarization, it can be recognized that the Black Lives Matter movement is providing a healthy cultural critique and creative use of pain, anger, and suffering to advocate for human dignity and positive cultural change. Furthermore, the principles of existential–humanistic psychology can be used to deepen the understanding of Black Lives Matter and other protest movements, while also offering important guidance on how to avoid various potential risks to the movement’s success.
