The irony is that Walt did set out to be a "steward" with SotS. He specifically brought in a Jewish-American producer (someone who could empathize with being a minority and experiencing discrimination) as he didn't want the film to be "Uncle Tomish" and full of racism. (his words, not mine; I am not being sarcastic, I just know some don't like that term, so I want that to be clear in my usage). Unfortunately, despite his efforts, prejudices of the day and societal pressure still led to SotS exhibiting some unsettling elements.
