"When an insurance broker tells you that SF doesn’t deal with the Real World, when a chemistry freshman informs you that Science has disproved Myth, when a censor suppresses a book because it doesn’t fit the canons of Socialist Realism, and so forth, that’s not criticism; it’s bigotry. If it’s worth answering, the best answer is given by Tolkien, author, critic, and scholar. Yes, he said, fantasy is escapist, and that is its glory. If a soldier is imprisoned by the enemy, don’t we consider it his duty to escape? The moneylenders, the knownothings, the authoritarians have us all in prison; if we value the freedom of the mind and soul, if we’re partisans of liberty, then it’s our plain duty to escape, and to take as many people with us as we can."
-Ursula Le Guin
