I have many doubts about the quality of that book ('The Boy in the Striped Pyjamas / Pajamas') - I thought it was dreadful with a most unconvincing narrator 😳
I've not read the novel, but I have seen the film, I thought it was 'ok' and I wasn't offended by it in any way.
In general. as far as the Holocaust is concerned, I do think it very important that young people today should learn about the atrocities that took place in the death camps during World War II. Hopefully, the more people know about these places and what went on inside them, the less chance there is of such things happening again.
I do not however, as some seem to do, believe that the list of twentieth century war crimes begins and ends with the Holocaust.,
In Cambodia, Pol Pot murdered one quarter of the population of his country, while the rest of the world looked on.
Nobody will ever know how many died in the pogroms ordered by Stalin - probably several millions
Millions died horribly during World War I - a war fought on behalf of the royal dynasties of Europe - the Hohenzollern, the Romanovs, the Hapsburgs and - not least - the Windsors.
Bosnia, Rwanda, Hiroshima - the list goes on, and that's without even mentioning Vietnam
So, yes, people should never be allowed to forget the Holocaust; equally, they must never be allowed to forget
all the atrocities that made the twentieth century the bloodiest in history.
