It was interesting and informative about different types of protest action, outlining their strengths and weaknesses. There were also some interesting things about bridging divides between different groups. However, I struggled with the author's confidence in the effectiveness of his ideas, particularly when discussing the number of people required to drive change. Unfortunately, some arguments felt simplistic and a bit naïve. I hesitate to be too critical, though, because the author is an activist who has driven real, positive change—something I can’t claim for myself. What do I know?
