I get quite angry when people get reductionist about history, usually because of story or narrative (pre-templated story patterns re-applied over and over again)
The beauty of history is that the same event can have multiple, conflicting, powerful narratives associated with it. Looking at these narratives challenges our understanding of our own humanity. If we're smart, we end up realizing as Solzhenitsyn did, that "...If only there were evil people somewhere insidiously committing evil deeds, and it were necessary only to separate them from the rest of us and destroy them. But the line dividing good and evil cuts through the heart of every human being. And who is willing to destroy a piece of his own heart?..."
And then we _really_ begin our study of history, humanity, wisdom, and the rest of it.
It's far too powerful to buy into a story and get blinders on. I think it's probably a great thing when beginning your journey, but you should never stay there. And if you're a historian stuck in a version of a story I'd argue you don't know your own profession.
