I have said "WE have gotten off track here. This is a good topic for another time, but we need to focus." Also with one student hassling another, "What you are saying is not appropriate. "we need to look at it from both perspectives, you need to see the other point of view. Stop, lower your voice, be respectful." I have said so many things, it depends on the personalities of those involved. Once I said "Who's in charge, what are their responsibilities?" " Who's at risk and how to proceed as safe as possible"
