I was not forced into liking the Huskers though I chose to be a Husker fan and my parents move to Iowa and I could not afford to go to school at Nebraska and honestly can hardly afford to go to Iowa State and that was one of the big reasons. But no matter what even though the Huskers are going to the Big Ten, Which i was opposed, I still will be a big 12 fan and will root for those teams to do well no matter what.
I'm not sure how old or what year in school you are but I believe, that once you've been through the rigors of school life and the ups and downs of your young adulthood, there is a connection to the university that won't easily be compartmentalized. Let yourself associate with the university and the "fan-dom" will follow.
I'm probably older than most on this board but I grew up in NW Iowa and liked the huskers and hawks. Why? Because that's the diet I was fed.
Once I came to school and people didn't know that I was (sort of) a hawk/husker ... it only took a few encounters (the reverse of what you describe) where I quickly learned to hate the fanbase of both.
I've witnessed a husker fan (2002) directly dis-respect my wife verbally and with a finger ... called security on that d-bag. Why? They couldn't take the loss -- plain and simple.
That said, in my section Saturday, people were civil - Huskers and Cyclones. I did make fun of Lil Red rather loudly. That probably ****** off a few huskers. But ... I mean come on, that is one lame mascot. Also, I'm thinking if the 2-point conversion had succeeded, this thread would be even longer and more descriptive.
It takes character and perseverance to be a Cyclone. It's easy being a husker.
