Necessity

I should modify and market a handheld spectrophotometer so that politically correct leftists are no longer put in this terrible quandry:

There have been hilarious debates at State about "who is black?" How many black ancestors do you need to be black? How can you prove it? (Note: Does this sound a little bit like old South Africa to you?) This debate got so exasperating that instructions went out to make racial categories "self-declared." One white male wag (now, we believe, either retired or about to be) sent in a message "self-declaring" himself a "black woman" and challenging the HR bureau to deny him that classification. Another one pointed out that half of his ancestors were women and demanded compensation for what they had suffered.
