racism varies by where you live, speak and look.
try being white in parts of hawaii or other nonwhite areas in the nation just like being the 'wrong' color in other places. however, racial 'purity' is on the decline.
also, a persons social economic status impacts how they are treated.
short, tall, fat, thin, good looking, ugly...the list is endless
talk to a sociologist if you want more information (my wife was a sociology major) or just travel a lot
even the way you dress varies how you are treated.
