I'm going to make this REAL simple for you, (as they say in America), and I would like a straight 'yes' or 'no' answer because it's really not rocket science.
You have two equal candidates in your analogy, A and B. They are of equal merit in some photo finish type interview which simply cannot be called either way.
Without mentioning which colour you have just favoured, (yes FAVOURED), have you or have you not just discriminated against one of the two candidates based on his or her colour? Yes or no RogueHanger???
You see, I would much rather pull their names out of a hat in the name of fairness rather than colour because, wait for it, that is racism by definition no matter how you sugar-coat it!
I put it to you, sir, that you are more racist than you think you are, how you portray yourself and how much you think I am.
Hec, I thought this would be much harder than it was when I suggested he start a different thread on this subject. But he's finally shown his true colours and my work here is done.
