I don’t really know what you’re referring to at this point.

I’m saying:

• A regular flat pizza is not a pie. It does not have a casing, and the “filling” is a topping, as you say.
• A (Chicago-style) deep-dish pizza is a pie (more-so than a pizza in my opinion but whatever) because it has a bottom crust with filling on top (a pie according to Wikipedia). That’s not lunacy. It’s right there on Wikipedia, with even a link to Chicago-style deep-dish pizza.
• A calzone is a pie because it has crust both on top and on the bottom (surrounding the filling), as well as filling inside.

This is not “lunacy”. It’s just reading a definition and interpreting things to fit the definition. 🤷‍♂️ If you think that’s lunacy I’d hate to tell you about Pluto.

I’m going to refrain from talking about hotdogs, because I’ve yet to look up the definition of a sandwich, but I’d rather not at this point lol.
