"The National Congress of American Indians and over 1,500 national Native organizations and advocates have called for a ban on all Native imagery, names, mascots, terms, redface, arrows, feathers, and appropriation of Native culture in sports. The joint letter included over 100 Native-led organizations, as well as tribal leaders and members of over 150 federally recognized tribes, reflecting a consensus among Native Americans that Native mascots are harmful."
