In all fairness, a significant majority of the time the RT is quite respectable although it can get quite tedious with lengthy transmissions with needless information both ways.
However, things do get carried away and decorum and discipline goes out the window. I've personally heard shouting matches and asinine arguments over the most trivial of matters.
My golden rule is that it is a fairly anonymous environment (unless someone REALLY goes out of their way to ascertain the identity of crewmwmbers) and interfering in a dialogue only incurs wrath from the agitated party/ies. If two stations are slugging it out, let em have a go at it. It only exposes their inability to control their emotions and in turn their immaturity.
