Since the post is now too long for a tumblr mobile response...
And here we go with the white people hate.
1. I specifically designated uncontacted cultures as exception
2. White people arent the only ones wearing these costumes. You think Mexican Americans dont go out as kings and jesters? You dont think black children go out as European pirates? You think little asian children dont go out as French chefs, European dragons, or knights? Why do people like you find a white person dressed as a samurai as racist, but a Japanese person dressed as a knight not to be?
3. Oh., you get mad that some white people cant tell Asians apart? Can you tell the difference between a Criotian and a Turk by looks alone? What about an Austrian and a German by their accents? What about Romanians and Russians? People freqyently get British and English people confused. The typical assumption on Tumblr is that all white people look alike. But here you are acting like the same thing doesnt get done to them. And do you think people in asia and Africa always get the races of other people from their country right?
4. You sound very similar to OP. Your focus seems to be on crapping all over white people for the same actions of other countries, cultures, and “poc”. You are against generalizing other cultures and people, but do it to people of European decent. With that line of thinking, you wont be convincing us of your supposed miral highground anytime soon.
