Yes, there really are a bunch of different issues at play, and I'm realizing that's true even more as I try to write about Allen's book than while I'm reading it! What she has so far talked the most about are really small and mid-sized cities in red states, rather than rural or suburban life—and that's a very interesting point you raise about suburbia. It reminds me of a book that's on my list but which I haven't read yet: Clayton Howard's The Closet and the Cul-De-Sac: The Politics of Sexual Privacy in Northern California, which sounds like it addresses queer suburbia (or the queer implications of suburbia) more directly.
