Oh, i'm sorry. I just thought you would have a similar vocabulary to
Ricky so i was just helping you out by using words straight from his mouth instead of making you translate back and forth.
A proof covers all bases and if there is any counterexample it is no longer a proof, I was just saying the likelihood of the US having more authentic pizza is greater due to the greater Italian population. The two most popular forms of pizza are New York and Chicago, which coincidentally have their roots from Italian immigrants. Also, demand couldn't really be used as a counterexample to that, as we are comparing authenticity/the best pizza not popularity. All demand would show you is the cultural demand, but as it is affected when the product is altered to fit the cultures tastes, all demand would show you is where pizza is more popular, not the best.
Have you ever been to the US and the UK to experience these things first hand? How often do you go?
