This story echoes Mildred's "Seashell ear-thimbles" (i.e., a brand of in-ear headphones) that act as an emotional barrier between her and Montag. In a 2007 interview, Bradbury maintained that people misinterpret his book and that "Fahrenheit 451" is really a statement on how mass media like television marginalizes the reading of literature. Regarding minorities, he wrote in his 1979 Coda:There is more than one way to burn a book. And the world is full of people running about with lit matches. Every minority, be it Baptist/Unitarian, Irish/Italian/Octogenarian/Zen Buddhist, Zionist/Seventh-day Adventist, Women's Lib/Republican, Mattachine/Four Square Gospel feels it has the will, the right, the duty to douse the kerosene, light the fuse. [...] Fire-Captain Beatty, in my novel "Fahrenheit 451", described how the books were burned first by minorities, each ripping a page or a paragraph from this book, then that, until the day came when the books were empty and the minds shut and the libraries closed forever. [...] Only six weeks ago, I discovered that, over the years, some cubby-hole editors at Ballantine Books, fearful of contaminating the young, had, bit by bit, censored some seventy-five separate sections from the novel. Students, reading the novel, which, after all, deals with censorship and book-burning in the future, wrote to tell me of this exquisite irony. Judy-Lynn del Rey, one of the new Ballantine editors, is having the entire book reset and republished this summer with all the damns and hells back in place.
