Speaking as someone who roots for probably the 2nd-most hated sporting entity in America, it just doesn't lead to anything positive to play the "why, oh God why?" game with people who hate your team. Asking why and pointing out that your guys do things the 'right way' and all that jazz won't change anybody's mind. I like Duke, certainly more than UNC, but especially on a day when they were playing a popular mid-major for a title, it seems silly to complain about people rooting against them (and this was more about Dickie V's complaints than Duke's fanbase proper).
