I am a relative oldie, too, but I don't hate Texas. I have been going to TCU games since 1963, the the 60's and early 70's were the glory years for UT, and with TCU going from mediocre in the 60's to awful in the late 70's, lots of lopsided UT wins then. Still, I really don't hate them. I have worked with and been around UT people all my life and have never had a problem.
But except for the fact that a win over Texas really meant something, I always wanted to beat Baylor more and would pull for Texas over Baylor, especially in the Teaff era. In the 80's after aggy would beat them the week before we played them, Teaff would whine about the officiating in his TV show, then play us and we would get royally done in (trying to avoid the auto censor there) by the officials. BTW, Teaff and Sherrill were the only ones who were really offended by Wacker's letter to the coaches. That should tell you something. Also Baylor was always the dirtiest and worst sportsmen we played every year. It looked like they were trying to emulate Miami.
aggy, however: I have had incident after incident after incident with aggy fans and grads. Very in-your-face with insults. It's like 4 semesters of how to be an aggy jerk is part of the required curriculum. I would even pull for Notre Dame over aggy. Right now I would certainly pull for Baylor or Tech over aggy because BU and TT are in our conference.
So I will be pulling for Texas to stomp Baylor.
