I'm honestly not sure from your post if you agree with me or not though the Philly cheesesteak is a bit silly. There are people, call them sentimental, traditional, pedantic, whatever who do give a shit about such things. I do not. But for some people really into food, cooking, dining, call it what you like, original recipes do in fact matter. I do like to cook and eat and drink but if someone wants to put beans in their chili or a pinch of sugar in their tomato sauce/Sunday gravy or cheese on their Italian beef I personally don't care.
I agree on you saying you won't get consensus and I kinda expanded upon that.
But my main point is that I don't understand why people argue so hard on minor or major differences in how other people make/consume a dish of food.
Under ordinary circumstances you have a person making food that they name as something and another person finding a minor difference and blowing up about how the difference means that food isn't w/e the first person called it.
As long as that person does not require you to change your definition of said food item, why argue them to death over whether adding beans means it isn't chili?
You are 100% entitled to your opinion in my mind, so is the other person you disagree with, and at the end as you said, there is little chance of coming to any unified consensus on many of these things.... so why bother arguing it?
I mean it is food.... if it was a big social issue or economic issue.... how you label a social or economic system and what that means, those things can be very important and worthy of debate/consensus.
Food is not to me lol
