Why is pineapple on pizza something that people tend to love or hate?

I know some Italians and I have never heard them say "Gee lets have some pineapple on the pizza pie!" It's like the pineapple lost its way to the fruit salad and it should stay there in my opinion.

its a bit of sweet, sour and salty, some people just like that combo together. Its like the combo of sweet and sour pork/chicken, its sweet sour and a bit salty.

It tends to be rather juvenile, sort of like chicken nuggets.

pizza is good with anything on it

In Australia, it is not a Pizza or Hamburger without Pinapple

I liked it, because of the sweet and savory combo. However, I stopped since it's offensive to Italians and it's their food so...

I like it once in awhile

got me , why do people dislike pineapple !!!

I can tolerate ham and pineapple pizza because pineapple goes with ham or gammon. I can't have pineapple and something else, with ham absent.

Because pizza should Never be sweet. Just ask Any Italian Grandma
