My two cents,
As a history teacher, this is something I fight tooth-and-nail on. I have my students read Bury my Heart at Wounded Knee, the Diary of Anne Frank, To Kill a Mockingbird, and All Quiet on the Western Front. I believe these books are essential to understanding modern American and World History.
I speak to the parents every year, along with the school board and the principal. I have not been heavily challenged yet, even by parents of varying ethnicity, culture, and religion. We discuss these things and come to an understanding. I also refuse to jump onto the Politically Correct bandwagon, frankly I think it's tremendously overblown. I respect all students, parents, administrators, and everyone else the same. No one gets special treatment or consideration unless they earn it.
With the amount of books we're banning, pretty soon we'll be lighting the bonfires next.
