Pro-pineapple (but anti-hawaiian, should be pep, pine, jalaps) here: I’d try it, but only with chicken and Habeneros if I can, jalaps if they have no habs.
My theory on why people don’t like pineapple on pizza is that most of them pair it with sweet ham, so they lose the full effect of the spicy/sweet/salty combo. Pineapple on pizza is amazing, hawaiian pizza is an abberant form that should be removed off menus everywhere and replaced with the true god-king: The PPJ.
