Though I hope you recognize that no one is talking about the actual controversial topics the OP mentioned, right. It quickly derailed into discussion about pizza toppings which is only controversial if your entire personality is based on what you like on your pizza.
And also pineapple on pizza is sacrilege @darthmongoose, though not as much as mayo is. ugh...
@aqua03 the irony being that tomato is a fruit.
