I like pineapple on my pizza
That's a joke, right? What's so good about pineapples on pizza?
I love the pineapple because it tastes much sweeter than the tomatoes and the sausage
Some people love pineapple on their pizza, while others do not. It's perfectly fine to enjoy what you like.
But everyone else seems to think I'm weird because they don't like pineapple on their pizza.
It's only because it's a strange combination, but everyone's an individual so keep liking what you like! I'm sure that everyone has their strange food they like, you don't need to feel bad over it.
