Beyond the uproar this news may have caused because he is an Italian chef, mostly Neapolitan and with his own pizzeria in Naples, I appreciate his attempt. What I appreciate less is putting himself on the spot by saying 'Unfortunately, people follow the crowd and condition themselves according to the opinions of others, or what they hear".
It's not out of parochialism, it's that we in Italy just don't like pizza with pineapple. Of course I imagine that there will be someone here who may like pineapple pizza, but it is seldom, very seldom. To me his just seems like a poor attempt at publicity and wanting to make a difference by being a teaser, but in my opinion it's a flop.
There are many other foods from other countries that we love and we don't need the chef in question to teach us.
