I'm an Ole Miss alum. I wanted to chime on this.
Like renaming the buildings, getting rid of statues etc. Most people didn't care about that stuff or even supported it because most people are apolitical/one issue people and generally, the big ask was a lot of the traditions and identity, though we did get rid of some stuff like Colonel Reb (who has too complicated a history to go into here) in the late 90s (and fully in the 2010s) before the fervor among young people for this sort of thing. Wanting to drop the rebels name was the big ask, which was compromised on and eventually redefined fully but the name and wordmark was kept. Other things like Dixie were slowly worked out.
The problem was the new traditions that were attempted to be started were incredibly lame and artificial, like the black bear mascot. It's like the 'skins rebranding not being well received because the WFT is incredibly generic and lame. (Seriously, why not just do Washington FC if you were going to go that route?) The solution was tying something natural with winning football. That, and simply giving lesser known traditions greater prominence helps too, the student body loves this kind of stuff.
Trust me, if you ever get a competent AD, it will be fine and other stuff will emerge and maybe even stuff you didn't even know happened will be very fun and cool for fans and students alike and the atmosphere may even be better than before. Texas is a blue blood with the money to do this, much more than my school, I promise to all of you worried about it. And it's not like Eyes will stop existing, you can still listen to the records of it and other stuff that could be phased out from the band, I still have a flag with Colonel Reb on it in my rec room because it is part of the history of my school that I love and nobody is denying that, but it's just not fit for public consumption anymore.
Texas is a more liberal state and Austin is very liberal, so it will be fine, I promise again.
