Where did you go to school??
Well I do not wish to take anything out of context or appear contentious,so anyone should feel free to follow the original link and read the article in full.However my interpretation of the authors comments and question regarding yours were specifically formed from the following remarks by the author:
"There are just a few things about pizza I can state with absolute certainty.
1) What passes for pizza in North America, UK, etc. is a very tasty savoury pie. It is nowhere near what is really a pizza."
"Keep in mind that original, real pizza is margherita. Dough, Tomatoes, Mozzarella, Basil and Oil. No pineapple/anchovy/chili/dogfood combinations here."
"New York street pizza is a celebration of culinary greatness, but in the very "strict" qualification it does not qualify as "real" pizza. Don't get me wrong, I love NY pizza with pepperoni, mushrooms, etc. as a taste of its own and every time I'm in the Big Apple, I consume my weight in it, but IMHO there is something about the wood-fired oven original margherita simplicity that puts it in a league of its own. Yes, eat great pizza and you may not "live longer" but you'll definitely live happier!
