Anybody over forty and under a hundred got Hemingway in their HS curriculum.
No doubt, but the way Hemingway is taught is not standard by any stretch of the imagination. I'm Gen X. Hemingway's work was introduced to me in high school in a positive, though unenthusiastic, manner. In college and in graduate school, his work was marginalized and reviled. I found those who marginalized and reviled Hemingway were typically (1) women, and (2) limp-wristed artist wannabes who need to tear others down in order to build themselves up.
