C'mon, it's not like those T-shirts are officially liscensed by the Sox. When I went to DePaul, we had "ND Sucks" t-shirts for homecoming (with a clover leaf crossed out on the other side) but they weren't sold at the bookstore. My explanation of the rivalry is this: South Side inferiority complex thinly disguised as "neighborhood pride". Whether it be the town's love for the Cubs, disparities in income, local media's portayal of north vs south or whatever, South Siders have a chip on their shoulder. And like a petulant child who feels like the older brother is getting all of the attention, they "act up" to get attention. They bully, they behave badly, they gloat and taunt. How many people do you see wearing baseball caps or knit hats with "North Side" embroidered on them? How many Cubs fans will go down to US Cellular to boo the Sox during the World Series? The thing that makes Sox fans the maddest is when they try baiting Cubs fans into this silly rivalry and their attempts are met with complacency and a general lack of interest. The best way to deal with a bully is to ignore them, but every time a Cubs fan (on this board or elsewhere) bitches and moans about Sox fan behavior, it only feeds the fire. I liked the suggestion to go and congratulate all your Sox fan friends before they can gloat. You take away their fun that way.
