Most of them trying to cross aren't Mexican.

Arguing if pineapple should go on pizza versus whether or not it's still classified as a pizza are two different arguments.

No, no other culture gets so bent out of shape about it like Italians. Some Indian guy in England creates Chicken Tikka Masala and most Indians are like "yeah that's Indian food", some Italian guy creates Chicken Parm in America and Italians absolutely lose their fuckin minds when someone calls it Italian food.

Generally when other cultures talk about dishes, they're talking about styles of cooking, methods of preparation, not a specific set of immutable ingredients. An American can see someone putting onion rings and bbq sauce on a burger and still believe it to be a burger. If it were an Italian dish, they would insist it's only a burger if it has lettuce, tomato, pickles, onions, and ketchup, any other topping would render it something else, and you have to give it a new name. It's silly, and pretentious.

I love watching Italians get butthurt about food names.

Yeah, I'm trying to figure out wtf OP is talking about lol.

Another one that chaps my ass is representing 1-dimensional data with 2-dimensional areas. Almost always misrepresents the data.
