You want to be banished from Italy you propose pineapple in their pizza and see

Especially in Napoli

Mostly yes, but Neapolitan pizza hardly has garlic in it.
Basic margherita pizza only has 4 ingredients, dough (made only from flour, yeast, salt and water), crushed tomatoes (uncooked), basil and mozzarella cheese with occasional dash of pecorino / parmesan). The magic is in the dough and everything else is just complimentary.
