of characterisation and the effect that these conventions have on depictions of sexuality and gender. During the pulp magazine era (1920s-1930s), explicit sexuality of any kind was rare in genre science fiction and fantasy. Then, according to Joanna Russ, in the more relaxed Golden Age of Science Fiction (1940s-1950s) the genre "resolutely ignored the whole subject" of homosexuality. Some writers were able to introduce more explicit sexuality into their work as the readership for science fiction and fantasy began to age in the 1950s; however until the late 1960s few depicted alternative sexuality or revised gender roles, or openly investigated sexual questions. After the pushing back of boundaries in the 1960s and 1970s, homosexuality gained much wider acceptance, and was often incorporated into otherwise conventional SF stories with little comment. By the 1980s, blatant homophobia was no longer considered acceptable to most readers. In Lois McMaster Bujold's Ethan of Athos (1986), the titular "unlikely hero" is gay obstetrician Dr. Ethan Urquhart, whose dangerous adventure alongside the first woman he has ever met presents both a future society where homosexuality is the norm and the lingering sexism and homophobia of our own world. Uranian Worlds, by Eric Garber and Lyn Paleo, was compiled in 1983 and is an authoritative guide to science fiction literature featuring gay, lesbian, transgender, and related themes. The book covers science fiction literature published before 1990 (2nd edition, 1990), providing a short review and commentary on each piece. As speculative fiction gives authors and readers the freedom to imagine societies that are different from real-life cultures, this freedom makes speculative fiction a useful means of examining sexual bias by forcing the reader to reconsider his or her heteronormative cultural assumptions. It has also been claimed that LGBT readers identify strongly with the mutants, aliens and other outsider characters found in speculative fiction. James Jenkins of Valancourt Books notes that the connection between gay fiction and horror goes back to the Gothic novels of the 1790s and early 1800s. Many Gothic authors, like Matthew Lewis, William Thomas Beckford and Francis Lathom, were homosexual, and according to Jenkins "the traditional explanation for the gay/horror connection is that it was impossible for them to write openly about gay themes back then (or even perhaps express them, since words like 'gay' and 'homosexual' didn't exist), so they sublimated them and expressed them in more acceptable forms, using the medium of a
