Yeah, you can have bad fans on all teams. I think it probably stems from the long losing streak we had at the time, as I recall from 2000-2005, so 6 in a row. A lot of non competitive games in that era too, and a lot of bad losing seasons. No excuses for bad behavior, but hopefully it’s few and far between.
I remember my first A&M game in 1997, couple of Longhorns in our area. We generally left them alone, and they cheered for their team and we cheered for ours. They were smack dab in the middle of hostile territory, I remember thinking they were brave.
