But the most ridiculous examples I've seen were about food. Unfortunately I can't find any right now but basically the idea is that it's inappropriate to make something that's not of the same origin as the chef.
There is some merit in this. We have quite a few Chinese fish and chip shops in England, and I've yet to find a decent one. They are great cooks when it comes to traditional Chinese food, but they don't understand the simple concept of British fish and chips.
Fish and chips is indeed hard to find done right. I've had it in Sydney, but not found it done right in the USA.
But what about the problem of "cultural appropriation" being applied to Texas Barbecue?
If you are not aware, the basic indirect smoke method was developed by Native North American Indian tribes. Then the method of smoking baby-back ribs, was perfected by southern slaves, who were thrown the ribs, those being believed to be worthless.
Now everyone can agree that we can't have these great dishes culturally appropriated.
I propose thus that the technique of post modern historical revisionism be used to alter history, and solve this nightmare?
