You want to talk sports rivalries? This is the bull-goose loony rivalry of all time.
Both team historically challenge for the top of their league. They're both in the same city. One is traditionally Protestant, the other traditionally Catholic. One is considered working class, the other middle class. Their fans are insane to the point of deadly violence.
And they've been going at it for more than a century.
Make the Red Sox-Yankees look like a schoolyard squabble.
