No, sorry. We are FAR beyond the point of saying a 50+ year old woman who has lived in the United States her whole life (I assume) just needs some more education to know that it is not appropriate to go out in public in blackface. What if she had gone as a Nazi officer, in uniform? What if she had dressed like a KKK member? This is EXACTLY the same, and if she doesn't realize that, shame on the UO for ever having hired her in the first place.
