The mindset of the left is so laughably shallow, it's hard to even fathom sometimes.
So, you can only cook food from your own culture? What defines a person's culture? What if they come from more than one culture? What if they don't know what their culture is/who their ancestors were? What if they are from a mixed culture family? What about when first world culture is stolen from by third world cultures? Is it only bad for white people to enjoy other cultures, or does this rule apply to all races? Can an Asian open a taco stand, or is that only banned for white people? Can a Mexican open a Chinese restaurant?
Again, the mind of a hard leftist is just a bizarre train wreck of shallow ideas that are in conflict with each other, because they were so poorly thought out to begin with.
