How does one do this, anyway?

So, I offer a prospective LJ-meme for people to consider.

In some strange parallel universe, you have just been selected to perform a rather unusual task: you must choose a book to be utterly expunged from history. (You don't have to do the expunging, just choose the book.) There is a condition: you aren't allowed to delete a totally unimportant book that's been forgotten anyway - the book must be something widely considered a 'classic'; that is, one that lots of people have read (or at least heard of and felt they should have read), and is felt to be in some way 'significant'.

What classic book (fiction or nonfiction) do you choose to retcon out of reality, and why?

(Answers welcome either here or as posts on your own journal in the hope of spreading!)

(I'll post my personal answer tomorrow; I do have one ready:)
