I suppose if it entices people to read this classic, it's all for the best. But please don't claim that Fitzgerald intended this as the factual basis of his book. Thompson remains unfazed by such criticism. Bruccoli's career is invested in Gatsby being white. She looks at Hemingway and Cather but not at Fitzgerald.
People bring in new ideas.
That is the way the world works. Thompson situates the book within a racially charged historical context. In 1924, the Johnson-Reed Act excluded immigrants of African descent from entry to the United States. But he doesn't cite the publisher. Which happens to be Fitzgerald's own Charles Scribner's Sons.
