Same here. In Spain this kind of costumes (with the painted face) were quite common during the carnival party in February (maybe they still are, I haven't attended to the party for a few years). The same way we have another public holiday on December where 3 disguised guys give presents to the child, one of them is black-skinned and as in many little towns or cities there's no volunteer to do the job, most of the times someone paints his face (the role is always a male, at least traditionally). So I can understand if someone don't understand the problem with this, if I think about the costumes I'm used to see in carnival it's pretty obvios that the roots are racist and the way they portray dark-skinned people is offensive and caricaturesque, so I think it's nice to slowly make people think about it and correct it. It should also be nice for some USA people to stop thinking that they are at the center of the world, and that other countries may not associate this to racism.
