There is always someone who is going to be offended by something, I just hope this woman was more offended by the idea that real children are living in cars and the street than she is by the idea of a muppet being used to show kids that such things do exist. Kids don't have to be taught that, for all too many they hear it on the news, or from their parents discussing the funerals of the kids down the block who are killed in drive bys. Or their own mother struggling to make a living and still keep her Medicaid.
The reality of poverty and suffering isn't lost on them even at five. And for those kids who don't see it, or know it, yes, it can be upsetting, it should be, they should turn to their parents and say "Mom, what can we do to make it better?" We'd all be a lot better off doing something than just wrapping our kids in cotton batting.
It's amazing how education, and awareness are considered 'damaging' these days. Because this person is 'mourning the loss of ignorance'(rather than innocence). The book isn't graphic, it does show kids in real situations though, and kids are perfectly capable of putting a perspective on a realistic image of a kid living in poverty, it was literally written with help from Child-Psychiatrists so there's even a scientific backing that the book is age appropriate.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
