I blame message boards and my weak makeup for the ever changing hatred I have for other cbb programs.
I grew up despising Duke, UNC, and Kentucky because they were the bluebloods and the media loved them. I also did not like Umass. There was always a healthy respect for all big east teams (yes, even Georgetown, BC, and Providence).
After 1999 and 2004, and coupled with the fact that I actually have started to like Coach K a little and that JC seems to really respect him as well, Duke is no longer on that list.
I rooted for Syracuse hard against all of those big 12 teams in 2003 and was happy they won it over Kansas, but I find their message board fans excruciating. Many of my good friends are Cuse fans, but they aren't whacko.
What Kentucky is doing right now just doesn't seem very real, so they don't bother me that much. I'm just waiting for them to get burned.
In short, I've come to dislike Syracuse, Pitt, and Villanova for some reason more than any other teams- I think it's their fans.
