Most people don’t care enough about the latest outrage to give up their bus ride or caffeine unless it’s a close friend that has been insulted or jailed. So there is a tool that activists have long relied upon to compel protest, even when a group of people don’t necessarily want to participate. It’s a form of persuasion that has been remarkably effective over hundreds of years. It’s the sense of obligation that neighborhoods or communities place upon themselves. In other words, peer pressure.
