The title just shows what happens when you take something out of context. It's just part of a quote from a panel Publishers Weekly held in its “Think Future” series. "The panel, sponsored by Kensington Publishing, included Sherman Alexie, author of The Absolutely True Diary of a Part-Time Indian; Dara La Porte, manager of the children’s department at Politics and Prose in Washington, D.C.; H. Jack Martin, assistant coordinator of young adult services at New York Public Library; and George Nicholson, senior agent at Sterling Lord Literistic; it was moderated by PW children’s reviews editor Elizabeth Devereaux." [Full disclosure: I kind of wished they had picked an author who had written more than one YA, but maybe that's just me.]
What Alexie said in full was: “I thought I’d been condescended to because I’m an Indian,” he said. “That was nothing compared to the condescension I get because I’ve written a YA novel.” He said that fellow writers have also accused him of chasing a lucrative market. “Because I’ve written a book about a 16-year-old,” he said, “that means I’m a capitalistic whore."
A lot of authors feel disdained if they write mysteries, or sci-fi, or YA, or anything but literary novels.
