It would be difficult for a writer of realism to avoid suggesting a political/moral perspective in his or her fiction. "Politics" per se is absent from my writing but there is usually a moral (if ironic) compass.
I don't teach literature from my perspective as 'Joyce Carol Oates.' I try to teach fiction from the perspective of each writer. If I'm teaching a story by Hemingway, my endeavor is to present the story that Hemingway wrote in its fullest realization.
