The only thing that is blasphemy is that there are people who apparently think they have the right to decide how I eat my pizza. Now the picture above is too much pineapple for my taste, but I do enjoy a Hawaiian pizza (which does contain pineapple) every now and then. When I'm really in the mood for Hawaiian pizza I think it's delicious. (I really must be in the mood for pizza in general, plus I cannot eat pizza too often regardless what is put onto it, due to my gallbladder being removed).
And that some people would loathe me for that is something I couldn't care less about. I'm the one who's got to eat that damn thing.
I've seen people put winegums and other sugar candy on their pizzas. Now that is something that disgusts me to be honest, but if they wanna eat it, fine... As long as I don't have to do it.
