Is pineapple on pizza acceptable?

This irrationally controversial question has divided households since the advent of Hawaiian pizza. Gordon Ramsay decisively says that pineapple has no place on pizza while Alton Brown is a staunch defender. How do we decide which reality cooking show host is the expert?

This is exactly what happened last week when a Republican legislator took the words of disability advocates out of context on the Iowa Senate floor.
