It's because it's easy to whip up an angry crowd. Anger is a temporary motivator so bad actors use it as a way to increase the likelihood of swarm behavior like brigading. There are also some people who enjoy being part of brigades because it makes them feel like they have a social group that does important things. That's why the same people often go from cause to cause without ever making a noticeable change beyond complaining. It kind of sucks because they feel like they're special and march to their own tune but often they're being played by whichever piper is in town.
