Cartoonish caricatures of minority races are racist. Please, post here the first images of Zwarte Piet, which all of you acknowledge were depicting blacks and post a picture of the modern rendition of Zwarte Piet who is supposedly no longer representative of any living human race. Please point out how the imagery has changed. What began as a racist caricature has remained completely intact.
As an optional question. Aside from clothing what specific traits characterize the "Sinterklaas look". What do you need to look like to pass off as Sinterklass.
Next, tell me, aside from clothing, are the specific traits needed to look like "Zwarte Piet"?
They look for a large part the same. But like I said the meaning given to the look is totally different now than it was in 1820 or something.
It's very specific. Basically the one you see in the OP. Zwarte Piet? Well considering that 90% of his body is covered in clothes, it's blackface, or more precise brown face.
Note that that isn't perceived as racist in The Netherlands.
