How far will this go? Will the film Viva Zapata be banned because Brando wasn't Hispanic? What about the film Broken Arrow where Cochise was played by Jeff Chandler (not Apache to my knowledge).
The University of Colorado at Boulder did this too. Not only did they ban the items mentioned above but they also banned cowboy costumes too. I don't know who would be offended by the latter. Cows? Horses? Probably cows. Drovers are not looked upon favorably in bovine history books.
