Yeah, that has never been my argument. Nationality =/= race.It's not impossible to be Nigerian and white either. The point made sense. To me, it was a comment on reasonable expectations in a small village in a rural area.
However, Nigeria was brought up as a counterpoint to the OP's discontent with living in a small white town under the presumption that all racially homogenous places just turn out the same, when that is just not true because different racial categorizations carry different sociopolitical weights in our current society, and thus, the cultures will develop differently from that fact alone.
