Right, but which skills do EVERY member of the culture have, the Intelligence skills? Because this ethnicity is more intelligent than the other ethnicities?
Stereotyping an entire culture for EVERY member always goes wrong. It is impossible to avoid racist implications.
And it isnt just what the stereotype says, it is also what the stereotype fails to mention. The generalization obscures what is actually happening within a culture.
Sweeping generalizations for every member of a culture, are unrealistic anyway. It isnt what a culture is, nor how a culture works.
Each culture is inherently diverse. Multiple conflictive trends are going on at the same time.
The way to represent a verisimilitudinous culture is to make it out of the diverse background institutions that construct it.
The culture adapts and evolves by adding new trending background traditions and retiring unused, archaic and obsolete, background traditions.
