Wrong. This is fucking wrong.
First it is not just sweet and salty. It is salty and fruity. That is not the fucking same. If it was, there also wouldn't be pushback on the salted watermelon shit.
And you can't just pick off pineapple. Sure you can remove the piece of fruit, but you can't remove the juice that has became part of the pizza. Most shit is like that even on something like a burger. Like with pickles or onion. Sure, you could remove them, but the taste is still there. You can remove the item but not the taste. That also applies to pepperoni. The grease is now baked into the pizza. You can't remove it.
Also, on top of all of that. The pineapple is that cheap canned shit that tastes like fuckin' ass. Maybe if it was fresh cut pineapple I would be more willing to accept it as a topping. But it isn't. At at least at all the places around here, all the pineapple is that canned shit. I've had pineapple on pizza. It is bad. It taints the pizza.
