All combined, you're meant to be upset at the preparation while also feeling threatened. "I love pizza! Why is this brown man making a pizza in a way that so heavily clashes with what I understand a pizza to be? He's not even good at it, look how he put a hole in the dough! Is this what it's going to be like if there are more brown people in my country? That's terrible, how dare they destroy this food I love! Maybe the rightwing party is right, I can't believe the left is inviting these fucking foreigners into the country to destroy everything I love!"
Why are you pretending you don't understand this? Did your boss not explain the kind of work you would be doing, komrade?
