The death of Christopher Hitchens is a loss to the world of letters for, as the many eulogies over the last week have proven, he was clearly a stylish writer, a fantastic orator, and from the accounts of those who knew him, a voluble, generous and compassionate friend. But as the last line of Some Like It Hot makes clear: "No-one is perfect." Given that Hitchens never stood on ceremony, and was a great slayer of sacred cows, it wouldn't be fitting to note his passing without decrying one of his more otiose and unfortunate legacies: as the inventor and populariser of the term Islamofascism.
