My son's College class had twins (male) that had one black and one white parent. They applied at the college, one listing race as Cauc. the other Negro/black. After they'd been at the school for a while, it dawned on some bureaucrat.....so they explaned there was no 50/50 choice! Still irriteted , they backed off.
HOWEVER it was onlyb because they had someone else to jump. There was an African student there who had applied as African. He was curlly headed, true, but he was blond (natural) blue eyed of Dutch Ancestry from SOUTH AFRICA. He'd been given a "minority" slot, and the bureaucrats were outraged. Eventually, he won the argument and the bureauracy was forced to back down.
Oh, the 50/50 kids were in the Shakespear Play "A Midsummer Night's Dream" and were great hits, they played a single part. Can you guess which irt was?
