Based on very limited interactions with Aggies in the Bay Area (a total of 3 in last 20 years): it initiated with them getting to know that I went to UT and their first response is that they don't like what goes on in Austin and is said with a searching glance, as if to discern whether I am getting their drift and agreeing with them. When they see that I am (deliberately) not catching their drift and ascribing their question to mean UT's recent poor football season (and they have been plenty over the past 2 decades), they immediately put me down as the enemy. In other words, it is "othering" of UT/Austin in the fullest sense, politically, religiously, culturally, etc. The psychosis sets in when the enemy, fully in the evil camp, is somehow excelling in what they hold dear. This is like evil triumphing over good. The only way this can happen is that the evil is temporarily too powerful and the good will rise soon and vanquish it. Even if the temporary period lasts decades and centuries, good is axiomatically good and evil, however successful, will always be evil.
