Attempts to overturn orthodox accounts of national identity fall back on other kinds of exceptionalism. Even refutations of exceptionalism often do so (if the orthodox version of history is exceptionalist, the refutation will typically be exceptionalist).
Refutations of exceptionality that emphasize "normality" can be even more noxious, however. You can't escape exceptionalist discourse simply by saying Spain is a "normal" country like any other. It may be the case that it is "normal" in the way that every other culture is, that is, based on contradiction and anomaly. But so is Italy or Norway.
