Pineapples leak a good deal of their disgusting sickly sweetness into the cheese/crust which is absolutely vile. On top of that, each one creates a little pus filled crater of filth that ruins everything it can secrete and spew it's repulsive bile into. They have a texture that doesn't mesh at all with toppings or the pizza itself and still taste sweet even if cooked a lot, they just get dry, which is even more disgusting. The thought of caramelizing pineapple in cheese should give any God fearing man a chill up and down his spine and a desire to rid the world of such evil There are also several meat dishes that can be made with a sauce with strawberries even though it isn't my thing. By the same token, there are also many meat dishes that utilize pineapples. None of them resemble at all a pizza, not even remotely close, even all the horrific variations on the norm seen in these threads, especially considering they're often transformed a great deal by cooking (for example a strawberry sauce) or (ideally) used very sparingly (al pastor).

Pineapples on 'za are absolutely unacceptable and the only people who I could possibly see enjoying such a thing are children. If an "adult" likes this they are either a manchild, an idiot or both and should be at the very least shot on sight with extreme prejudice. 

There is nothing I hate more than pineapples on 'za. 'za is a beautiful thing, even considering some of the strange incarnations seen in this thread. But there are some lines that should never be crossed, and this is one. If this is the hill I die on so be it. My convictions are strong and righteous. If the Rapture happened right now I promise you the first to be sent into the deepest pit of eternal hellfire would be the loathsome cretins who dare to ruin 'za, a sacred dish, in the most atrocious, offensive manner humanly possible. 

In short, fucking kill yourself you subhuman scum.
