Poet and author Tiffany Midge recently wrote a critique of racist iconography which offers a light-shedding look at two subtly different forms of racist icons, i.e., coöpted icons and constructed icons. Her critique questions the validity of "Taking Back Tigerlily" as an activist direction for Native American liberation.
"Rehabilitation" means "to return to a state of being useful". Midge argues that the concept of "rehabilitating" the icon of the Indian Princess Tiger Lily and the other racist images, e.g, Little Black Sambo, Aunt Jemimah, et al, is fundamentally absurd since these icons were originally invented from whole cloth for the express purpose of neatly anchoring racist stereotypes for easy consumption by [ethnic North-Western European] members of the mainstream majority. Hence, by definition, "rehabilitation" or "taking back" such images can only mean something vaguely like returning them to their original function of ensconcing and promulgating racism.
Some images are best forgotten...perhaps.
