did you really not see this coming?
of course this is going to start a war between people with good taste in pizza toppings and know what they're talking about and people who, well, simply don't.
pizza is a delicate art. you're supposed to enhance the natural flavour of the pizza, not fight against it. a pizza's flavour is supposed to be rich and delicious from the moment you take that first bite to the very last bite of the crust.
you see, pizza is like a first date. not in the sense that you strive to impress the pizza, that would be stupid. it's food. however, much like a first date, you treat that pizza well. do not overwhelm the pizza with too much; it only leaves a staggeringly bad taste. you only give the pizza enough topping(s) that make sense enough as to not destroy its natural flavour but really enhance it and bring out its natural beauty.
you see, saying that pineapple is good on pizza is like admitting to your first date that instead of the the clothing they purchased off say, saks fifth avenue or nordstrom (expensive department stores for non-americans), they would look better wearing something off of their local thrift store.
while there's nothing wrong in principle with thrift store clothing, you don't make those sorts of comments on a first date. it's insulting and makes you look pompous. the pizza will respond in turn, and deliver multiple swift kicks to your internal balls, in this case your stomach.
it's no wonder people like gimme are so hopelessly lost here. so many kicks to the balls and it's apparently the expected norm.
