Final answer:
Dr. Collins does not provide a direct statement on heterosexuality, but related discussions point towards the questioning of heteronormativity and the acceptance of sexual diversity influenced by psychological research and LGBTQIA+ advocacy.
Step-by-step explanation:
Dr. Collins does not specifically comment on heterosexuality; however, the context provided indicates a discussion related to the concepts of heteronormativity and sexual diversity. The field of psychology has debated the categorization of homosexuality and gender nonconformity, as evidenced by the APA's historical listing of homosexuality as a mental disorder in 1952, which was later challenged and removed. Gender performance and the social construct of sexuality are highlighted in Judith Loftus's comments from 'Huckleberry Finn' and Eve Kosofsky Sedgwick's research. The global LGBTQIA+ movement and cultural diversity in sexual practices show an evolving understanding and acceptance of various sexual identities over time.
Texts that illustrate characters constrained by compulsory heterosexuality include modern and classic literature where characters must navigate societal expectations based on their assigned gender roles. For instance, 'Huckleberry Finn' can be interpreted as a critique of gender performance through its characters' actions. Recent scholarship and movements have increasingly advocated for a broader understanding of sexuality, free from the constraints of heteronormativity, which has been perpetuated in some societies and cultures.
