Book excerpt: Gun rights and control are well-trodden subjects, with prior work supporting the right of citizens to own firearms, discussing the failure of gun control efforts, or warning about or exhorting citizen gun ownership, among other things. Although social media in their many forms have only come to dominate modern U.S. life during the past decade, there has been little academic exploration of gun owner communities on the Internet and social media. How do gun owners use social media? How do they meet other gun owners online? What do they talk about as relates to guns? With a massive and well-organized collection of support material, Guns on the Internet faces these questions with an unbiased approach that seeks a foundation for mutual understanding. Also available as an audiobook.
