If only the PTA ladies had the reading comprehension of 5th-graders. It's not the kids who need the shielding. I might have a talk with kids who are reading such things, but the idea of censoring them is just stupid.
There was never a hint of such controversy in my high-school's library. Because no such book would ever be allowed within a mile. A teacher was even fired for loaning a student one of her college text-books. I learned about many of these "classics" by hearing other students talk about them in college.
(There was one thick hard-bound bodice-ripper on the shelf only because it was a historical novel that was set in our town. It had a fairly graphic sex scene in the middle
I'm pretty sure I'm the only person who ever read it, and I didn't tell anybody.)
I do have a small collection of boys adventure novels from the 1930's (family hand-me-downs) and the casual racism in some of those is really shocking. It is valuable though, in showing how people thought and why things happened in those times.
