Rosenberg has it all wrong in his synopsis of John Ford's Western classic "Stagecoach": The Indians were the villains in that film.
John Wayne and the other immigrants were heading West looking for a better life, bringing only their diversity with them. They were greeted, however, by hostile and xenophobic Indians. The Indians, fearing a loss of jobs to the new immigrants, demanded they leave. Wayne stressed the importance of multiculturalism, but the Indians refused and started shooting. The immigrants fled, giving up their dreams of immigration.
