For me, UVA is the epitome of a program that I want to hate but just can't. They're frustrating to have to play all the time, but we've caused them some pain too, and their fans have always been classy. Tony Bennett also seems like pure class, so it's hard to hate them.
I also went to a game there in 2007 and was treated well despite being a loud (respectful, but loud) opposing fan in the lower bowl surrounded by UVA fans. I was standing up cheering after our big buckets, and nobody so much as yelled at me to sit down. That said, part of the respectful part was always being back down in my seat before they were into the front court so I wasn't blocking people's views.
Like if their fans were even slightly rude, I'd easily loathe the program. Instead, I respect them, and root for them in the NCAAs if it doesn't impact us.
