i am appalled at the premise of having a white side of town and a brown side of town. i would not support this, in any way, or seek to uphold it at all.
but, i need to make the point clear: i'm not white.
my father was of mixed jewish, native american, italian & french background. he also seems to have had some deeper ethnic ancestry, which may have been african american or southeast asian. it's not clear. we just know there was some very dark skin in there.
my mother is finnish & celtic (irish/scots/welsh) - technically white, but not really considered it through most of this continent's history.
for 10 months of the year, i am full on brown.
