Historian Marc B. Shapiro blogs:
While at least since Jacob Katz’s Exclusiveness and Tolerance scholars are now no longer deterred from studying the medieval Jewish view of “the other”, there is still great reluctance to examine contemporary views, for fear of how this might play into the hands of anti-Semites. I am curious to hear what readers think about this. How long can we keep all of this “under the carpet,” and should we even be attempting to do that?
Ruth Langer has discussed the medieval tradition in her new book Cursing the Christians? A History of the Birkat HaMinim (Oxford, 2012), p. 12:
For Jews engaged in dialogue, it has been much easier to identify the problems within Christianity than to turn that scrutiny back on our own heritage. Jews, after all, were very much the victims, not just of the Holocaust, but also of centuries of Christian anti-Jewish venom and oppression. Consequently, traditions developed among those studying Judaism in the wissenschaftflich mode to obscure embarrassing elements of the tradition rather than to confront them. . . Christian anti-Judaism in its many expressions led to Jewish responses and attitudes that were equally vicious; the power relationships between the two communities prevented Jews from expressing this with physical violence, but Jews still lacked respect for their neighbors. . . . In our time, Jewish publishers are restoring uncensored versions of many texts, reclaiming a difficult heritage. While from an academic perspective, this has merit, there has been all too little discussion about its impact on the Jewish community.
I would, however, dispute the use of the expression “equally vicious.” Once Langer assumes that it was Christian anti-Judaism (and I would add “anti-Semitism”) that led to the Jewish responses and attitudes, then I don’t think it is correct to portray them as “equally vicious.” The one who is responding to widespread murder of his coreligionists, and responding only through the pen, cannot be regarded as “equally vicious.” Furthermore, considering the oppression that Jews suffered in medieval times, all the anti-Gentile sentiments found in texts from this period are completely understandable.
