I think this is a valid interpretation, however it isn't the only one. Consider that you dressed as Zwarte Pieten in a parade, and then afterwards went in costume for a drink in a bar with predominately black patrons. The problem with that situation points to the problem with other valid interpretations of Zwarte Pieten. If elves were real, there would probably be some issue taken with the American custom, and definitely with Keebler Cookies.My point is, the Zwarte Pieten are the elves of Sinterklaas. They help him to complete the monstrous task ahead of them. Dutch children see Zwarte Piet as American children see the elves of Santa. As the helpers who make everything possible.
I had this wonderful, well thought out reply with pictures, references and deep thinking points to consider. When I hit the reply button, I lost it to a bad gateway error. It is now lost. Unfortunately that reply used up most the the brain power allotment for today. I will try to re-create it later on today perhaps.
I try to alway remember to ctrl a, ctrl c my long, thought out responses before I submit. It's happened to me so many times on reddit or here, especially when I was on stolen wifi. Random timeouts would steal my soul so hard.
Thank you for the reply. I really haven't thought about Zwarte Piet in a bar setting (or any non-sinterklaas related setting), mostly because it doesn't happen as far as I know. It is not a good idea to walk around in costume if you don't want to play the part, since the kids will come to you asking for candy or to relay a message to Sinterklaas. And in case of a bar, a lounging Sinterklaas or Zwarte Piet is not part of the story. They have work to do. You are right tough, my interpretation isn't the only interpretation, but I would like to hear the other interpretations instead of "Look at what they do! This is racism!" without an explanation.
