Debates about "authentic" children's literature often focus on the question of who can legitimately write children's literature. Therefore, an author's age, race, and/or ethnicity, (dis)ability, and sexuality become important considerations in establishing credibility and authenticity. If we define children's literature by authorship, then perhaps, as critics like Rose and Zipes suggest, adults cannot write "authentic" children's literature. However, as children's authors such as J.K. Rowling and E. Nesbit claim, adults who remember their own childhoods (such as Rowling and Nesbit) do have a right to tell children's stories. Other critics focus on how marginalized identities are portrayed in books through their thematic content and characters. Concern over misrepresentation and stereotyping has created a push for books by "insiders" who tell their own stories and experiences. While controversies surrounding authenticity are forcing nuanced discussions about identity, authorship, and audience, some critics are pushing back at the label as a limiting framework.
