The world recently learned that the estate of British author Roald Dahl actually allowed a team of censors to purge words and phrases from the author's works that they deemed "offensive." This is a terrifying escalation in the left's war on the literary record and on artistic expression in general. The idea that censors could reach back into old books and rewrite them would have been unthinkable even a decade ago. It is communist thought-policing, pure and simple. Every writer or artist should be taking steps now to protect their work from tampering by potential future vandals.
