Honestly I think most pizzas would ick me out more than a pineapple topping.
Pineapples are probably the one topping not found on my standard preference of pepperoni that I find pretty much inoffensive. I mean, I wouldn't go out of my way for it when I can get the balanced flavor of pepperoni pizza, but it's inoffensive. It's just pineapple with some of the flavor cooked out, it's not veggies or suspiciously non-pepperoni meat or something.
I have so many other problems I could have with a pizza aside from pineapple. There's pizzas that have been charred, pizzas with way too many herbs in the sauce, pizzas with way too much sauce in proportion to the cheese and toppings period, pizzas with blatantly cheap ingredients, pizzas utterly soaked in grease. . .
If you're going to hijack a perfectly good pizza, I'd probably be most OK with pineapples out of anything, LOL. Not even sure what this silly war is all about and why everyone seems to feel a need to take sides.
Heck, here's another idea: dessert pizza. Use sugary dough, some kind of fruit glaze or maybe apple butter or something for sauce, icing or something for cheese, then put the pineapples on top. There you go. Sounds like it might need a bit of refinement to work but then I just thought it up on the spot, LOL. I know fruit pizzas are a thing, though.
