What is a good hook to start off a paragraph about why certain books should not be banned from schools and libraries?

Explanation:

censorship goes against the very values that are the reasons for the ban in the first place

if a book is offensive to you

it goes against your values

it brings about a feeling of being offended

if this is by design by the author (like mark twain/) then youd be banning someone who agrees with you

if an author is offending you on purpose (like hitler in mein kampf)

then you are depriving others of feeling that way because now the book is banned

you are also depriving others of disproving others who agree with offensive material

those who agree will feel special having offensive material because now it is "underground" so to speak

soviet union ran into this problem when they banned american/western literature

needs an explanation
