[citation][nom]quotes[/nom]The peculiar evil of silencing the expression of an opinion is, that it is robbing the human race; posterity as well as the existing generation; those who dissent from the opinion, still more than those who hold it. If the opinion is right, they are deprived of the opportunity of exchanging error for truth: if wrong, they lose, what is almost as great a benefit, the clearer perception and livelier impression of truth, produced by its collision with error. ~John Stuart Mill, On Liberty, 1859[/citation]
Nice try, but this is far from a literary "opinion". Yes, if it were a scholarly dissertation on the merits of pedophilia, it would not be silenced, as it would be facilitating a conversation. This book isn't that.
And don't forget, the book is published. Getting distro on Amazon.com is not a free speech matter.
