What metaphors are used in Custer Died for Your Sins: An Indian Manifesto by Vine Deloria?

"A Redefinition ..." is essentially an expansion and/or an elaboration on the author's statements advocating Indian unity, with the anecdote about the Tiguas serving not only as a powerful example of perseverance in its own right but also as a metaphorical summing up of what the author repeatedly states throughout the book. Literally surrounded by white influence, the Tigua maintained their tribal, social, and cultural integrity. In short, and as the author repeatedly states, with faith, courage, vision and self support, transcendence of white oppression is possible.
