Because PC and UConn never played when you were at UConn. Have you ever went to a game at the PCC? Have you ever left a game after UConn lost? You live 100's of miles away so I imagine your contact with PC fans is limited. I think these are a few reasons you don't understand.
I've only driven through Providence. I grew up in a family of UConn, members of my immediately family, my in-laws, numerous cousins, nieces and nephews, and, of course, many friends have gone through Storrs. I attended my first UConn basketball game when I was in grade school. I've attend Pee Cee games not in Providence. I remember when UConn Pee Cee meant a great deal, beating them in '76 was huge.
I was a young obnoxious drunk in stadiums all over this country. Had shouting and shoving matches (no punches) in post game parking lots. I've had the shoe on the other foot. But even then, when it was over it was over. At this point considering the bifurcation of our programs, the fact anyone can be so upset at frairboys, well, it just seems silly. But you are right. I don't understand why anyone would care what they think, do, or say.
