You have to take into account the fact that the large majority of the hate stuff is nothing but humor--for most fans, I think. I love college hockey no matter who is playing and frankly don't get very bummed when the Sioux lose. It's more fun, though, when you can also give and take a little guff. That's why the titles are not that big a deal. The season gives us a lot of great hockey experiences, while the occasional banner is more of a bragging right than an experience. The bragging right means next to nothing to me now, except for the good natured teasing it is useful for.
Besides, it's harder to really feel the old Gopher hate when gopher players have been getting smaller, weaker and slower every year. I'd include uglier, but there has never been much room for change in that regard.
