Reading comprehension is a valuable skill. There are probably books you can read with exercises to help you develop this skill. (Xmas present request?)
I didn't say race was of "no consequence", I said it doesn't make one different or "diverse".
Say you do 1,000 blind interviews of black, white & Asian met thruout, lets say, New York City, do you think you'll be able to guess their race by their answers? Or will you just be shooting in the dark?
If you interview people worldwide race will be even less able to be determined by even the lengthiest questionnaire (a black guy from Stamford, CT is going to have stuff in common with his peers locally and very little in common with his doppelganger in Zaire).
Who someone IS is diversity. Your culturally background is certainly contributes a large piece to shaping who you are. Is it all that you are? Not even close.
We know - because we've tested it - that nearly everyone (not just white people) will come up with a different answer if they try to 'rate' the candidates in the knowledge of their ethnicities, or even their names, than if they do so blindly.
