I think you hit the nail in the head right here.
I do like pineapple in my pizza, but sometimes the pizzeria uses canned ones that taste 10x sweeter, and that is too much sweet and clashes with the rest.
In other words:
-“pineapple in pizza, aye or nay?”
-“depends on the pineapple, actually”
Why should I care what other people put on their Pizza?
Why should other people care about what I put on my Pizza?
That being said, the best pizza I ever had (this was when I worked for Pizza Hut, so it wasn’t a menu item, it was something we came up with for our personal meals):
Thin crust, medium salsa (instead of Pizza sauce), onions, ground beef, cheese. Run it through the oven. After cooking, sour cream, shredded lettuce, black olives.
I think we need to go deeper to be truly controversial than pineapple. We should all admit that Italian (esp Neapolitan) pizza is inferior to pretty much every pizza out there, be it American (New York or Chicago style), the cheap ones made by Turkish immigrants everywhere in Europe or whatever. Glorifying the purity of toss some leftovers on bread dish eaten mostly by the poorer classes as some sort of higher art form frankly sickens me. Luxury is where it’s at!
