I don't much care what other folks choose to put on their pizza, nor do I care what style of pizza other folks favor. Deep-dish, Neapolitan, NY-style, Detroit style, tavern style-- all can yield a darn fine pizza-consumption experience.
Personally, I don't love pineapples on pizza. And I don't love the so-called "BBQ pizzas" which tend to be grilled chicken with some overly sweet "BBQ sauce" and maybe some red onions. And I don't like the square cuts that get goop on my fingers. And I definitely don't like having a raw egg cracked over my pizza as it's served to me...
But if other folks like that stuff, who am I to tell them they shouldn't do it?
