There are times when I bitch about it, but many more that I dont. Carolina fan's bitch about it every single game they lose. A lot of times even in games they won. I have never once heard a carolina fan say: "Congratulations, you guys won that game. You deserved the win and outplayed us." Always a thousand excuses as to why you lost. Somehow you all don't grasp the fact that there are games where other teams play particularly well, or you play particularly poor. Its always the ref's fault.
If I felt like it I would go back and pick out posts in which I have said "Congrats" to whoever we lost to. Whether it be a UNC loss to Duke or NCST(football) or Butler's loss to Duke in the title game. May have only been once or twice, but that doesn't mean I haven't accepted the loss.
And once again, you are describing every fan base. In every fan base there are fans that won't congratulate the other team, will bitch and moan about calls and won't accept the fact that they were beaten. So stop molding every fan into one giant blob. Cuz if we did that then I could come on here and say that you Duke fans always bitch and moan about calls that weren't called. Nor do I every hear "Hey congratulations on the win, you beat us"
But I don't, because I tend to listen to the people who actually know what they're are talking about when they watch basketball, not the dumbass gloating fanboy.
