To reduce the shoah to the killing of puppies and kittens is sentimentality in the face of near absolute evil.
I can understand you don't want to face near absolute evil, who does? But to reduce it to sentimentality is an insult to all the victims.
The rest of us set about doing something about near absolute evil and we formed the United Nations and adopted the Universal Declaration of Human Rights.
There is nothing sentimental in the Universal Declaration of Human Rights, and nothing about puppies and kittens.
