I'm on tvtropes.com and in the YKTTW a trope was recently proposed called "Minority in Appearance Only" in which a show has a minority character who "has no accent and their taste in music is no different from the rest of the (white) cast." This struck me as odd considering there are roughly 3 (or 5 according to traditional anthropology) "races" for the hundreds of hundreds of countries and cultures out there ... "accent" and "taste in music" is an obviously ridiculous way to show something like "race". It seems more related to culture. This view of race/culture would lead me to believe that African-American's would simply have American culture, which is probably true for the most part, but sub-cultures do exist, so my question is: Does an African-American sub-culture exist that I should be aware of? One that isn't best typified by accent/music? (Especially since my setting is a fictional U.S. city in an alternate history/reality version of the 1920s/30s in a plot revolving around organized crime with very little room for small talk ... the accent would be different anyway and music probably isn't going to some up at all). Basically, I'm trying to avoid the "WASPs painted ethnic" phenomenon without resorting to something that strikes me as both over simplified and at conflict with my setting. To be a bit more clear with what I'm looking for I know someone who wound up committing a faux pas when she was in Germany not over her accent or music tastes but over offering to help her host in the kitchen; a polite gesture in America ... an invasion of privacy in Germany. Thus in writing a German character I would keep such a differing view on proper social behaviour in mind. Anything like that I should know? Most of my other minorities come from actual foreign countries (like Germany) and were easier to research.
