Does The Boy In the Striped Pyjamas deal with the sensitive subject of the Holocaust in an appropriate way?

Yes, I do think that The Boy In the Striped Pyjamas by John Boyne does deal with the sensitive subject of the Holocaust appropriately, because The Boy In the Striped Pyjamas really represented the Jews and how it was like in a camp.
Shmuel was skinny, tiny and you can see that there are young, old, and sick people here. Towards the end it shows that there it was very horrific in the camps and that the Jews get hurt, bullied, and killed for no reason. Also the author told the truth, he didn't make it all up.
Another reason why it delt with this subject in an appropriate way is because John Boyne used child's eye view to tell the story. John Boyne showed us how the children during the Holocaust got 'brainwashed' and how they didn't know what the camps were like and who the people were inside. For example, Gretel got rid of all her dolls and changed them for maps and pictures of Hitler and Germany, as she was indoctrinated.

As Bruno said in the novel, "What are they all doing there?" This makes a lot of sense. Why did the Jews have to go into the concentration camps? They never did anything wrong.
