Disclosure: Many years ago while attending NU, I worked briefly - in a laughably minor capacity of charting pitches - for one of the Chicago MLB teams. No particular rooting interest for either now, however.
Why is there need for such sniping at each team from the other's fans? Both Cubs and Sox can be successful; not a zero-sum matter. Being a fan of one doesn't mean having to hurl childish and deprecating barbs, as they play in different leagues.
Wouldn't it be great for the city, and the game itself, to have a 21st century "El Series" with both teams competing for a World Series crown?
You must not be from Chicago. Sox fans despise the Cubs. Knowledgeable cub fans, free and far between, dislike or simply code to ignore the existence of, the Sox. Most Cubs fans have no idea a game is played at wrigley and go for drinks and babes - so they also probably don’t even know the Sox or MLB exist.
It is has it has always been and, like the 100+ years of losing on the north side, how it shall be again.
