I am writing a Western scenario about outlaws being hired by a native tribe to protect a sacred site from The Incorporation and their logging/excavation crews.  And while there is a certain amount of violence inherent to that premise, a large portion of the story is also about freeing the Incorporation's workers and building a united front between the abused workers and the natives in the area.

The whole thing blends together several pieces of history, including an up-close lesson about the ruthlessness of robber barons and Frontier fundamentalists, bits of history from Blair Mountain, references to real-world figures like Bass Reeves and Theodore Roosevelt, and even has some Cherokee myths and language.  Would the fact that there's still violence inherent to the scenario disqualify it?  Or is it acceptable to just give the party (or parties) work-arounds outside of the most extreme cases?

Side note: This scenario was written specifically for a college class, but can likely be adapted to be appropriate for high schoolers.  I'm explicitly advising in the scenario not to go younger, due to the violent themes and the general complexity of the subject matter.
