I was kidding ofc, but let me explain. Italian's taste for foods and the balance of its flavours is remarcably different from that of americans/english etc. Much of the italian food adapted and "popularized" to fit your tastes looks to us as it's been distorted in a way that we find nonsensical, random, disgusting, atrocious. A bit like when you let a kid mix random stuff. So: it's not because of cultural purity, but because its modifications act on tastes that we don't find appealing.

Take a milkshake. Let's make-believe that milkshakes are the most typical and historical food from wherever you're from. Now take a beer-flavoured milkshake with raw anchovies as a topping. A different culture might find it tasty and attractive but you'd just find it... gross don't you? Is that a sign of close-mindedness or it's just a difference in tastes? What would you think if people abroad addressed that milkshake as a typical milkshake of your own country

Italy right now is actually extremely active in food innovation, ofc built upon flavour balances that make sense to our tastes. Take this famous chef's work as an example: http://www.ristorantecracco.it/idee/

Also give a look to Massimo Bottura.
