I always get the feeling that what they're really supposed to do is grovel--to admit that it wasn't an honest mistake, but that they really were being evil, and that they've finally been caught and forced to own up. I don't think people are comfortable with diversity when it means that some people think it's totally okay to do something that other people would find horribly offensive.
I'm sorry if that's offensive. But that's all I'm sorry for.
