Ray Bradbury wrote about the dangers of censorship in this book, and his replies to his critics and editors of his work demonstrates just how deeply his passion ran.
The "Critical Overview" section in the links below has a number of strong quotes supporting the idea that Bradbury's primary goal was to make his readers aware of how culture without literature eventually loses everything that makes it humane.
Bradbury himself wrote in his 1979 Coda:
...Every story, slederized, starved, bluepenciled, leeched and bled white, resembled every other story. Twain read like Poe read like Shakespeare read like Dostoevsky read like--in the finale--Edgar Guest...Do you begin to get the damned and incredible picture?
...The point in obvious. There is more than one way to burn a book. And the world is full of people running about with lit matches...
The thing that makes Fahrenheit 451 so relevant today is that things haven't changed. People are still running about with lit matches looking for ways to burn books by dumbing down the literature and filling American minds with stuff and nonsense.
I am not sure how he wanted to respond but I think he may have wanted his reader to repect books for more than just paper, ink, and glue. I find myself very upset when people say "I liked the movie more or I never knew it was a book". I read a lot of book but I take my time and I want to try to understand what the author wanted to say. I think in the age of tv and video games we just dont have time. At the end of the story, montag memorize 1 book. He made the book a part of his life and I think we should appriciate being able to memorize more than 1 and make it a part of our life.
