Clippers fans hate Lakers fans with a passion, but Lakers fans dismiss Clippers fans and take condescending approaches like 'It's cute that you guys support such a joke of a franchise' and 'It's cute that you guys think this is the year that the Clippers won't fall apart,' which drives Clippers fans even crazier than they already are. You know those college cities where the townies detest the rich kids from campus, or a multicollege city where the kids from the less-respected college openly loathe the kids from the well-respected college a few miles away? That's how the Clippers fans feel about the Lakers fans. Pure hatred.
Replace Clippers with Sparty in that paragraph and Lakers with Michigan and tell me that doesn't just fit perfectly.
