This is a thought-provoking letter written by Kurt Vonnegut opposing the idea of burning books of young children, in view of transforming the system of education in America.  

Explanation:

In this letter, Vonnegut starts telling audience/readers the ideas that can have a negative effect, not only on the target person/individual, but also on a wider range because of its effect being new and historic.

Though in view of a change, Vonnegut argues that this act of burning books is not what we all should accept. In Paragraphs 7 and 8, when Vonnegut explains about how people feel it is their right to decide what their children must read, the author explains to them that it is true but doing that in an un-American way -  harsh, impractical, ignorant manner can cause a negative impact for them.

The author clearly states that people/nations who read books have been a part of development, improvement and liberation.
