Throughout their relatively short history, lesbian and gay movements in the United States have endured searing conflicts over whether to embrace assimilationist or liberationist strategies. The Lesbian and Gay Movements explores this dilemma in both contemporary and historical contexts, describing the sources of these conflicts, to what extent the conflicts have been resolved, and how they might be resolved in future. Rimmerman also tackles the challenging issue of what constitutes movement “effectiveness” and how “effective” the assimilationist and liberationist strategies have been in three contentious policy arenas: the military ban, same-sex marriage, and AIDS. Considerable attention is devoted to how policy elites—presidents, federal and state legislatures, courts—have responded to the movements' grievances.

Since the publication of the first edition in 2007, there have been enormous changes in the landscape of lesbian and gay movements and rights. The thoroughly revised second edition includes updated discussion of LGBT movements' undertakings in, as well the Obama administration's response to, AIDS/HIV policy, the fight to legalize same-sex marriage and overturn the Defense of Marriage Act, and the repeal of “Don't Ask, Don't Tell.”
