I am fine with anyone asking someone not to swear in front of their children. You can do that anywhere at any time. That is not what we are dealing with here. I am fine with anyone asking politely if they could ease up on the refs. But after it became clear they were going to do it, mocking them afterwards is always going to cause a confrontation. Every single time, especially when you go after the grandma.
We both know if you are sitting in RES that you wouldn't tell a Ute fan to quit yelling at the refs. So venue matters. If this situation was so egregious, why did it bother no one else? If it was simply where they were sitting, then move. Freshman girls basketball has plenty of room to watch games.
