Katie outlines several pros and cons of online activism. The pros are that it allows people to support causes from home efficiently, shows the impact of the internet on social issues, spreads awareness of issues and causes large online debates, and is effective for raising funds. However, the cons are that it can be misleading and spread misinformation, may have no real-world impact despite large online support, is seen as hypocritical as online support requires little effort, and online activists tend to be more passive and less informed than physical protesters.
