You're mistaking race for culture. Ridiculous, faux-African names bespeak a culture; dark skin does not. The culture one associates with such names is not one that values education or industry. A child named Quieshianiquita is not going to set the world on fire.
I'm sorry, but you sound bigoted.
One has no control over the name one is given at birth. If you judge someone based upon that premise, you are bigoted. At some point in history, even your name was strange.
My name happens to be Hebrew, so to all the "jew haters" of the world, I am unemployable - that is just ridiculous.
