" If all narratives are relative, then we are lost. Widespread anti-Semitic fantasies may have reflected the plight of Germans, may even have been their “soul’s version of the truth” in the post-1918 period, but they were still fantasies, and the failure to counter them, or to see the fantasies as themselves creating terrible political realities, proved totally catastrophic. Relativism doesn’t care to distinguish between the scholarly and the slap-dash, the committed researcher and the careless loudmouth, the scrupulous and the demagogic. For that reason, it is hard to see how an insistence on “proper events” can ever be said to be dogmatic, or a refusal to insist can be anything other than treacherous. Spike "
