Yes.
To me, the important thing is to at least try, because even the best of us can get hot-headed.
When you fail, you try to pick yourself back up and not do it again. I have tried after heated exchanges to mend fences, and in only once case of a Freeper with whom I had an extremely heated exchange and who was stalking me from thread to thread (and who hasn’t posted on FR in a year or two) when I tried to mend fences, had the equivalent of pulling back a bloody stump.
But it is important to try.
