Correction: there is no way to discuss the Holocaust or its attendant holocaust or even ask questions about it, in a modern setting.
But then the question remains, why is this subject so non-amenable to discussion? Why is it so sensitive? Some people got persecuted, this has happened many times in human history, so why is this one such a big deal, is one question I would like to be able to ask, without the usual vitriol being directed at the question.
Is it OK to question the reasons people anywhere are persecuted, and what the rationale behind persecution and oppression might be? If it is, why is the Jewish case not OK to ask about?
For instance what's wrong with asking why the Jewish state was founded, and what part the Nazi persecution played in this? Isn't there a more or less direct connection? What would the odds be for a modern day Israel if the Holocaust hadn't happened, for instance?
Pointing out the blindingly obvious, "hey, it happened", doesn't address the issue underneath: why did it mean they got a "homeland" given to them, to do with as they pleased? Or is it the case that the Holocaust played no part in its establishment?
