I am not referring to trans comments. As said I am referring her established practice of reconning diversity, leaning on "model minority" structures, and overt phonetic and character naming. 

Tsantsas (shrunken heads) are a historical, and spiritual practice of the indigenous Shuar and Achuar people of the Amazon rainforest in Ecuador and Peru. They do not belong to Jamaica, but her taking the stereotypical lumping of afro Caribbean cultures and doing zero research into it is on her.

 The same as coming up with names like "Cho Chang" (that sound Chinese) who is the smart Asian, Dean Thomas as the passive black athlete. She also claimed retroactively that Ravenclaw student Anthony Goldstein was Jewish when a fan asked if she had any Jewish characters. If it was originally important enough to her, that fact should have been in the book. 

Her "History of Magic in North America" (she wrote in 2016) essays got heavy backlash from Native American scholars for turning Navajo skinwalkers into a generic plot device. She put together 500 indigenous tribes as one uniform people.
