Nothing is ever totally conclusive with the exception of death and taxes.

Thank you for a comprehensive, interesting and balanced summary of thinking on this immensely important issue. I have read some material on the Holocaust including survivor accounts (though nowhere near as much as John). What struck me was how many apparently ordinary and decent people either turned a blind eye to mass murder or actively participated.

The recent explosion of antisemitism, including rationalisations for violence against Jews, looks scarily like the preconditions to the rise of Nazi thinking that ultimately led to mass murder. It is imperative that we understand where the Holocaust came from if we are to stop it happening again.
