I can understand that but I think this is where you and I fundamentally disagree. I don't believe sports are inherently supposed to be family friendly. Just
9% of college football viewers are under the age of 18, obviously even less are under the age of 14 (which I'm arbitrarily designating as the age where cuss words are no longer abnormal to hear used). Do chants containing expletives necessarily enhance my viewing experience? Probably only minimally at best (good for a chuckle or two), but overtly banning them for less than 9% of the audience is unnecessary, in my opinion. It just breeds frustration with the many fans who like the tradition. Like it or not, they do contribute to the atmosphere at a stadium. Alabama banned Dixieland Delight and ended up bring it back last year due to the demands of their fans. I'd also argue a majority of fans are made once they are college students than when they are children but that's purely anecdotal from me.
There's been concerted efforts to make everything more family friendly in the past decade, or so, and it has only coincided with decreased fan participation across the board. Correlation does not equal causation but it is just one additional contributing variable. College football, and some other sporting events, tend to be an event where people drink and let loose. You are still more than welcome to bring your kids to the game, I just don't believe it is everyone else's responsibility to regulate what your child hears at a college football game. It's on the adult to explain to their kid they will hear things they are not allowed to say until they're older, when they can make that decision for themselves.
