Well, they probably just don't like pineapple! Slapping a pizza underneath it isn't gonna help.I just feel that at some point you have to accept that while you really like Pineapple on Pizza, they really don't like Pineapple on Pizza, and no amount of discussion on the virtues and hows of Pineapple on Pizza is going to make them change their mind.
Anyhow, more pineapple for me.
PS: Have you ever tried white pineapple. It is SO MUCH BETTER than regular yellow pineapple. But, it can't be shipped. I was in costa rica and some folks gave me two white pineapples. They said, eat this one as soon as you get back to your resort. Tomorrow will be too late. Eat the next one tomorrow. It isn't ripe yet, but in two days it won't be any good. Someday I might travel to where pawpaw fruit grows so I can try that, too.
