I think book booking is just wrong. Plain and simple it's wrong. ShrowdedPoet said it correctly+nod+ I'm sure most of the people here know what it's like to write and take some pride in anything written, imagine having an entire book of yours burnt, it'd just suck, it's completely rude and ignorant.
And even though book burning is bad, I think it's not as big an issue as book censorship. Groups that burn books are often looked down upon by everyone but those involved as radicalists, where as people who simply forbid people in their group from reading the book are not nearly as disdained for it, but it establishes the same effect, people are cut off from the knowledge in the books.
If someone is old enough to read a book and understand it, they deserve to read it, otherwise how would they grow in knowledge? So many books that are part of the education structure now were deemed as vulgar or satanic or wrong. Shakespeare's a pervert, To Kill a Mockingbird showed what the Southern states wanted to hide, Lord of the Flies just made people worry about other human nature, all these books were hated by some group upon their release[and probably burned] and are now core in [at least Canadian] high school education.
I actually think book burning is my #1 hated +nod nod+ I'll leave you with a personal favourite quote that is relevant
"You don't have to burn books to destroy a culture, just get people to stop reading them."- Ray Bradbury, Fahrenheit 451
