It's because Sunderland haven't made a mark on football, whilst we gave the world The Entertainers, had Champs League football, broke the world transfer record and are always in the news. They managed to get 7th in the league and gave the world Kevin Phillips. Not to mention the difference in the cities. So it's easy to see where their jealousy and inferiority complex comes from - Newcastle is just miles better than Sunderland in almost every category.
