I think that Diversity Beans are an especially stupid idea. Six colors of jelly beans, six flavors but the flavors and the colors don't correspond. So you might THINK that a red jelly bean might be cherry but it could be lime or licorice! See?
Obviously the message is "don't judge by appearances." But is that, in fact, the real message of diversity? This seems like a deeply weird metaphor. "Diversity means you could always be unpleasantly surprised or disappointed. Enjoy!"
I guess I'm not convinced that the problem is judging by appearances ("She looks like a lesbian") but rather the difficulties that follow that categorization ("Lesbians only want to talk about fast pitch softball, better avoid her")
How to get people to address the actual person, not the category, that seems like the challenge. And I don't see any candy beans available to fix that one.
