genetic testing to determing ethnic heritage

this is an nytimes.com article (reg required) about how ppl are using genetic testing to find out their ethnic background. the story part of the article is about 2 guys who took the test and found they are 9% native american and 11% northern african. but they have always thought of themselves as white. their parents are white. and i know that white american males are the “easiest group to discriminate” against, but don’t they have enough of an advantage within the social order that they shouldn’t be allowed to do this sort of thing to get things like financial aid to colleges and such?

Something to say?
