I see a few who squelch channel 1. I wish that was not an answer, as there are certainly a high number of times I log on ch 1 and stay there.
Quite frankly, there is no really good answer. People will be people. I see pilots who really get caught up in the moment and they express it.
In a perfect world, everyone would just respect each other and talk nice. It would be quite boring, but there is the other extreme, which should not be tolerated.
There is happy middle ground, and one day, maybe it will be found.
