Personally, I don't much care for the terms "white," "black," or "little yellow devils."
Actually, that last one was sort of a joke - meant to point out that these labels based on skin tone are not very accurate. As has been pointed out - no one is really "white" or "black." And I rarely hear anyone described as "brown" or "yellow" or "red" anymore, though this was a practice in our collective, more openly racist, past.
The terms are so limiting. For instance, take our illustrious President, Barack Obama. He is labeled as "black" on a regular basis. I find this to smack of Jim Crow days and slavery labels. The man is half "black" and half "white" if you really want to insist on using those labels. But - this sounds like the old adage, "One drop of black blood makes you black!" What on earth? If we can call him "black" we could just as easily call him "white." I mean, both are accurate - or rather, both are equally inaccurate.
I have four biracial children. As genetics will often produce, each of them sports a different skin tone, as do my multiracial grandkids. As a group (seven, to be exact), my grandkids range from looking 100 percent Hispanic, to looking Arabic, to having blonde hair and blue eyes and looking like a tanned California prototype! But...are they "black," "white," or "brown?"
When my kids were growing up, we used to get a kick out of filling out their school paperwork, which always insisted that we pick ONE race to categorize them. I always left this portion blank, and on more than one occassion was called on the carpet for that by school personnel, who would INSIST that I complete that section - which clearly stated "Pick ONE race." I always refused and told them, "So - what are you going to do - refuse to let my kids into the school Monday?" It was ridiculous.
We live in a racially diverse society - get used to it.
I don't have a good answer to these labels of "white," "black," or whatever, because I find "African American," "Chinese American," etc. to be cumbersome as well. Usually what I do is simply try to categorize them in some other way, if the need arises - like, for instance, "You know, the girl in HR with the dredlocks," or "That guy in accounting who always wears those goofy shoes."
