Use of Richard Connell's "The Most Dangerous Game" challenged in Colorado middle school.

From Blogging Censorship:

For the handful of you who did not read this story in middle school, “The Most Dangerous Game” is a 1924 story that satirizes the big game safari hunting of the 1920s and is often used to teach a number of literary devices.

In a local news report, the parent was quoted as saying the story made her son “uncomfortable to read it and to think about killing someone else”.

As Blogging Censorship points out, that's kind of the point of the story.
