It might be an ACC thing versus SEC thing. A lot of people still don't understand why a lot of the SEC teams band together.
First, I love college football. Any given Saturday, my 'teams' might change depending on the current scenario. I got to see my first game at the Rose Bowl a few years ago... UCLA vs SoCal... Was I just supposed to sit there and not cheer for a team? I bought a UCLA hat and enjoyed seeing the smug SoCal fans attitude get smothered slowly throughout the game.
Secondly, the default for most SEC team's fans cheer for other SEC teams. But there is a * with that... everyone has different experiences and that has weight on who everyone pulls for. One of my best friends graduated with me at USC but got his doctorate at Florida. I've had a blast every time I've been down to Gainesville whether the Gamecocks are playing or not. On the other hand, I absolutely hate Georgia and have actually pulled for Clempson a few times because of my deep seated hatred... but then my feelings for Tennessee has changed from loved to watch a Tennessee game to even pulling for Georgia to beat Tennessee because of how their fans have acted the last two years. It's a whole buffet of craziness that doesn't make sense. But that's ok with me and most SEC fans. The lines of hatred get drawn weekly during the year.
Lastly, you have a lot of people that have family and friends that branch through lots of schools. My family is purely Gamecock with no one going to any other school. My friends on the other hand are mixed between every one of these schools for various reasons; Clempson, NC State, Coastal Carolina, CoC, Furman, Georgia, Georgia Tech, Florida, UNC, Arizona, UCLA, App State, Wake Forest, Tennessee, Vanderbilt, VT, Alabama, and Penn State. Even with this list... at various times in the last ~20 years I've enjoyed watching some of these teams play football for various reasons. Mississippi State, Texas A&M, Wisconsin, Michigan, Nebraska, Miami, and Oklahoma.
I don't have any problem someone trying to say that they are ALL IN with one team. If you have that attitude, you probably don't get invited to watch football on the weekends.
If you got hidden trolls, out them
