The inherent direction was that delineating class by color coded identifiers was to signal that it is reflective to racism but not acknowledged as such, yes. And I agree, it does lack representation for Latino and Asian populations. Indigenous women are also not addressed. Both the novel and the series are problematic, in a few different directions. The reference to puritanical history was a subtle way to highlight the racism inherent in Christianity. Which is a separate issue all together to treat elsewhere. The root of this society is backed in scripture, it wasn't the only thing to address here though. As far as the series, I acknowledge it attempted to make amends early on in the article. However, it is sort of the cinematic equivalent to saying "I have a black friend".
