If you can‘t take the words as they are, the author failed to convey their meaning. All you are doing now is asserting that anyone with a different take on it than you is “not thinking for themselves”, which is condescending. I‘m not interested in saying anything more to you.
This is the one for me too. I felt sick for a while after finishing it and the worst part was that I could understand how people could do this to each other. The sort of dehumanisation that happened in past genocides.
