They live in a bubble. They're enabled and supported by state government (Campbell is a big FB booster AND the chair of the BoR, appointed by Abbott), and that's all the backing they think they need. They will absolutely not back down because they believe they don't have to.
Maybe the B12 censures them in some way, but even that would prob get tied up in court well past the season end. I just don't see a team dropping them from any currently scheduled games. Tech might regret it in the long run, tho.
