Pretty cool being racist. I noticed people from varying ethnic backgrounds seemed to land in particular divisions (maybe schools in those countries focused on these cores), but I wouldn't ascribe nationality to anything as broadly as you did.
I don't particularly care what their ethnicity happens to be. Just write good, bug free code that does things people want. How they get to there from here? No f'ing idea -- but I know that first they have to have to want to and they _clearly_ do not.
