For what actions does Oluo thank the reader at the end of the preface?

At the end of the preface, which Oluo wrote one full year after the publication of the book's first edition, Oluo thanks the reader for taking interest in the book, for having the courage to enter difficult conversations about race, and other such actions. She adds, "Above all else, thank you for using these conversations to motivate and guide real action, action above talk, to deconstruct White Supremacy and begin to heal the great harm it has brought upon us all" (12).
