When Jack London was told that he was too radical to write for The Atlantic:
London continued to send manuscripts to The Atlantic, but by now, his fiction was earning him better rates at other magazines. His Atlantic submissions were non-fiction articles defending labor unions and advocating an overthrow of the United States government. In a 1905 letter, Perry explained that London's radical writings were not suitable for The Atlantic's audience:His left-wing tendencies were the basis of London's The Iron Heel.
Forgive me for saying that many passages of the paper read precisely like editorials in one of the Hearst papers. These editorials are very ably and brilliantly adapted to the kind of people who read Hearst papers, but it is not the style of address which we can profitably adopt in The Atlantic. I know that you will forgive this unasked criticism, for I do not wish to take refuge behind the conventional editorial formula in your case.
London answered Perry's letter, making it clear that he saw the rejection as essentially class-based. But he made a point of thanking Perry for his respectful tone. "Now this is not sarcastic at all," wrote London, "and I am thanking you for the best and most genuine rejection I ever received in all my life."
