No worries, this pearl clutching is getting many books that we read in school banned as well.
And they've always been being banned for these things. And these are just from the <100 Newbery winners.
Thats the only book I've read out of the ones that you shared. Interestingly, that was the book my 3rd grade teacher decided to read aloud during storytime. When I read it again as a teenager I was questioning the choice, but even at age 8 I thought it was well-written.
I should read all the other books you listed.
