Not a melting pot, nor a mosaic, America is a Pizza.
The exotic toppings give it the flavor, the zing and pizazz. Some stick with one (pepperoni forever, though it’s forbidden to many), or we mix and match according to our preference. Salty and sweet, spicy and sour, strictly vegetarian for some, everything but the kitchen sink for others. My family are the feta and olives (we are still unclear if they belong on a pizza or not) my wife’s family the ham and pineapple (natural enough to seem like one singular topping to some, unacceptable to others). The toppings may touch and overlap, but each remains distinct for the others. We do not mistake ham for olive, or onion for pineapple.
