The not-quite-concluded racial drama playing out at Indiana University-Purdue University at Indianapolis (IUPUI) in the last months can't be ranked with the embittering rape charge scandal at Duke that so recently mesmerized the nation. And as news it's not in the same league as the total war waged against Harvard president Lawrence Summers for having had the temerity to suggest that factors in addition to prejudice might have something to do with the underrepresentation of women in math and the sciences.

Still, what happened at IUPUI is a pungent reminder of all that's possible now in the rarefied ideological atmosphere on our college campuses – and in this presidential election year, not perhaps only on our campuses.

The story began prosaically enough. Keith Sampson, a student employee on the janitorial staff earning his way toward a degree, was in the habit of reading during work breaks. Last October he was immersed in "Notre Dame Vs. the Klan: How the Fighting Irish Defeated the Ku Klux Klan."

Mr. Sampson was in short order visited by his union representative, who informed him he must not bring this book to the break room, and that he could be fired. Taking the book to the campus, Mr. Sampson says he was told, was "like bringing pornography to work." That it was a history of the battle students waged against the Klan in the 1920s in no way impressed the union rep.

The assistant affirmative action officer who next summoned the student was similarly unimpressed. Indeed she was, Mr. Sampson says, irate at his explanation that he was, after all, reading a scholarly book. "The Klan still rules Indiana," Marguerite Watkins told him – didn't he know that? Mr. Sampson, by now dazed, pointed out that this book was carried in the university library. Yes, she retorted, you can get Klan propaganda in the library.
