I think the problem with your approach is that no sane person would publicly defend racism. Because they would be outing themselves as a racist to all of their co-workers. I believe that I understand very well WHY people have racist points of view. Racists are incredibly common and their motivations and beliefs aren't a mystery. I'm not sure what you would hope to change by talking things out. Prejudice is by definition irrational, because it involves pre-judging. You can't really reason with someone about an irrational belief.
