There are several fan activist groups that have created platforms to promote social change . The three that have attracted a significant amount of research include the Harry Potter Alliance , The Racebending Movement , and the Nerdfighters . The Harry Potter Alliance ( HPA ) consists of more than 100,000 members who support several causes including Doctors for Health , Free Press , and The Gay-Straight Alliance . This movement , which was established in 2005 by its non-profit leader Andrew Slack , parallels Harry Potter 's endeavors to combat Voldemort to the broader society 's goals to challenge dominant power structures that oppress marginalized groups.The HPA has been active in its strides toward providing financial relief toward populations in need . For example , following the 2010 Haiti Earthquake , the HPA assembled to raise approximately $ 123,000 to provide five cargo planes that supplied medical resources to the country following this momentous event.The HPA also organizes its members into four Hogwarts houses to strengthen group solidarity and encourage members to spread awareness about social and political issues . Like in '' Harry Potter '' , these houses compete to earn points based on their abilities to inspire change and encourage direct action . Following the release of the 2010 live-action film , '' The Last Airbender , '' the Racebending Movement emerged to promote racial diversity in the Hollywood film industry . The film received criticism for casting white actors as the main characters who came from predominately Asian heritage . . As a form of protest against the whitewashing of non-white characters , a community of fans created the Racebending.com website to advocate the fair representation of minority groups . On this site , a large number of users post comments that instigate debates among active community members.This movement also has a strong presence on Tumblr where users cast people of color as traditionally white characters such as Bruce Wayne , Hermoine Granger , and Luke Skywalker . Hank and John Green created the Nerdfighters community in 2007 after gaining popularity from their Brotherhood 2.0 project where each brother posted a video to YouTube every other day for a year . Unlike fan activist groups such as the Harry Potter Alliance and the Racebending movement , the Nerdfighters community does not dedicate its efforts only toward promoting change . Rather , this community has a multifaceted creative output that incorporates music , fiction , and other forms of media with challenges , pranks , and games . The activities of the Nerdfighters community derive themselves from the work and interests of Hank and John Green ; for example , the community 's Positive Pranking Project consists of pranks that are similar to those found in John Green 's novels '' Paper Towns '' and '' Looking for Alaska . '' The commonalities that appear between Green 's books and the Nerdfighters include the objectives of establishing an environment that reinforces respect for others , intellectual and philosophical beliefs , linguistic play , and the goal to make world a better place for everyone .
