However, the relationship between black and white abolitionist writers was not without problems. Garrison supplied a preface to Douglass' "Narrative" that would later be analyzed as latently racist, and the relationship between the two male abolitionists deteriorated when Garrison was less than supportive to the idea of Douglass starting his own newspaper. That Stowe's book became an instant bestseller was in part due to the fact that she shared her readers' racist mindset, explicitly stating that black people were intellectually inferior and modeling the character of her protagonist, Uncle Tom, accordingly. When Jacobs suggested to Stowe that Stowe transform her story into a book, Jacobs perceived Stowe's reaction as a racist insult, which she analyzed in a letter to her white friend Amy Post.
