Great post.
Also, the folks in this thread who don't know what black face means, here you go
IT'S BLACK FACE
Her intent may not have been racist (I dont personally know her) but the deep rooted nature in our country of white people painting their face is. Shame on her for being insensitive to that.
"Such makeup" to me at least implies a little more than a simple painting of the face brown.
I don't see it as black face but that's because my exposure to the term and its effects is most likely a lot different than anyone in America or someone who has actually has been effected by this kind of stuff. I think growing up in a small Scottish town with very little diversity you are distanced from the more subtle aspects of racism with everything for a lack of a better term being more presented as a black and white situation where things are clearly defined as being not okay to do or say.
With that said she should have put a little more thought into what people would think of her costume with her seemingly being in some sort of limelight as with most situations where a "celebrity's" ignorance causes them backlash.
