Are High School Freshmen Mature enough for the word F*CK?

Students in the STEM Academy at Hardin Valley were assigned to start
reading a science-fiction book, called "Robopocalypse." Sam Lee, the
parent of a 14 year-old incoming freshman, is calling it
"inappropriate".

The New York Times best seller, written by Daniel H. Wilson, was published last year, it contains a fair amount of what some consider foul/ violent language.

"We want our kids to be civilized citizens and be upcoming members of community, and this does not serve that purpose," Sam Lee.

The school did offer Lee's child an alternative assignment to reading "Robopocalypse." Lee's child has the option to read one of two different books and then
write a paper on it instead of doing other graded assignments. Lee said
that option is "too little, too late."
