This chapter provides an overview of the three kinds of LGBT organizations at Christian college and universities – direct action groups, educational groups, and solidarity groups – and argues that a correspondence between the ethos of these groups and the identities of participants produces activist commitment. LGBT direct action groups protest their schools’ discriminatory policies toward LGBT people. Perhaps not surprisingly, these groups tend to be led by politicized participants. LGBT educational groups tend to fulfil dual functions – first, providing forums for their participants to collectively discuss their beliefs about LGBT issues, and second, organizing lectures, movie showings, and other events to educate the wider student body about LGBT issues. Because they do not presuppose a commitment to the cause of LGBT rights, these groups tend to be led by religious participants. Finally, LGBT solidarity groups fulfil two kinds of purposes – first, providing a confidential support group to assist LGBT students in their coming out processes, and second, organizing social events that allow LGBT students to meet each other. Because solidarity groups are focused on personal issues facing LGBT people, individuals who identify as LGBT most often lead them. The chapter contributes to sociological theory on activist commitment.
