The Absolutely True Diary of a Part-Time Indian question

I will preface this response by saying that I am not an English Education major and I very much dislike children, so I really have no business in suggesting what we teach America's youth. With that being said, after reading Sherman Alexie's Absolutely True Diary of a Part-Time Indian, I believe that it is definitely a text that should be taught in all classrooms at some point.
My reasoning behind this is simple; Absolutely True Diary hits on an extremely wide variety of teaching points, ranging from racism to depression and coping with death. While the novel does hit on some pretty heavy topics, such as eating disorders and drug abuse, in my opinion, that this is all the more reason to teach this book in classrooms. Providing a narrative that is not only relatable to students, but entertaining and witty, will most likely be more enjoyable for students than trying not to doze off during a video shown in health class. Assigning a novel such as this would ensure that they are actually learning, or, at the very least, show students who are struggling that they are not alone in the world.
It is clear from the beginning of the novel that Junior is extremely mature for his age. While he still has a tendency to goof off or lose his temper, he is very intelligent, and sees the world through the eyes of a realist. I believe that Junior's character would act as a positive influence, and cancels out the aspects of the book that could be viewed as risqué. He calls out racism for what it is, shows what drugs and alcohol can do to individuals and families, and paints an accurate, healthy picture of raging fourteen-year-old hormones.
