Incidentally, I am intrigued by how many European and Latin American writers expressed their political views in the columns they routinely wrote or write in the popular press, like Saramago, Vargas Llosa, and Eco. This strikes me as one way of avoiding opinionated fiction, and allowing your imagination a broader latitude. Similarly, fiction writers from places like India and Pakistan are commonly expected to provide primers to their country's histories and present-day conflicts. But we haven't had that tradition in Anglo-America.
