If you have not seen it, the Indiana University-Purdue University in Indianapolis (IUPUI) reaction to a university employee reading a history book almost defies parody. As far as I can tell, someone got offended or maybe was concerned someone might be offended because the Klan was in the title (notwithstanding the fact that the book is apparently decidedly anti-Klan). This makes the whole "niggardly" controversy seem well-targeted in comparison.
However, I think Jacob Sullum misses the mark when he says:
To clarify, then, Sampson was not in trouble because of the book he
chose to read. He was in trouble because of what he might have been thinking while reading the book.
In fact, this is still not correct. In fact, Sampson was in trouble because of what other people might think when they see him reading a book that has "KKK" somewhere in the title. Pathetic. Another lunatic step in trying to establish a "right not to be offended" at universities.
