I felt slightly uncomfortable reading Huck Finn too, BUT I LEARNED. I learned about America, and I learned about racial relations, and I learned about right and wrong.
Move Huck Finn to 11th grade? OK, kids are more mature then anyway, just NEVER remove learning a subject from the classroom because it is "uncomfortable." They're gonna be REAL uncomfortable when they learn what the Germans did at Auschwitz, but learn they must.
Yes, but the seventh grade is much too young to learn about Auschwitz. Maybe high school. At the college level, it must be a requirement.
