Sounds like a fun trick.... maybe? lol
I wasn't aware pineapple was controversial on pizza until a few year ago, when that became a meme on social media. I'd never heard anyone even jokingly say pineapple doesn't belong on pizza. The only real argument I've heard is that it's sweet. But we put sweet onions on pizza, we put sweet sauce on it, we put sweet tomatoes on there, and so on. Pizza can have sweet flavours sometimes! I mean it's like any topping, you don't have to add it. I don't add meat anymore. And I've never added anchovies, haha. To each their own. Maybe there's a life lesson to be found in pizza preferences and philosophy? Hehehe.
