Are these rapes by Anglos or other Indians?

I hope that it's not a racial thing, but I am reminded of an incident that happened years ago in Ohio. A couple young men came into the library were I was working. They wanted a picture of a "naked Indian broad riding a buffalo like they used to" to airbrush on the side of their van. I don't think they believed me when I expressed doubts about ANY Indian riding a buffalo; they left unsatisfied.

There seems to be a group of white males who seem to think that because someone's skin isn't "white" sexual activity is not only acceptable but probably deeply desired -- and a privilege by virtue of being "white."
