Us programmers often have a tendency to pedantry, and one of the reasons is because it's necessary to avoid confusion. So it's no surprise that there are sometimes comments stating that some usage of some word is wrong or could be clarified. I've written plenty of those myself, though sometimes I've handled it badly.
On the other hand, natural language is inherently subjective and ambiguous, and some people have strong opinions about what is correct usage that aren't that widely shared, and being overly pedantic, trying to be perfectly precise about the meaning of everything, is itself confusing. There's no such thing as a perfect way to word anything, and past a certain point pedantry doesn't really seem worthwhile.
In other words, if I feel that something I've written is clear enough, and someone suggests its not, I'll probably defend my position rather than immediately reword it. Maybe I'll get a better understanding of the objection when the commenter responds, and will be able to reword more effectively as a result, but it's at least as much about the feeling that if I automatically edit whenever someone objects, I'm confessing to a crime I didn't commit and in punishment I could be pointlessly editing forever.
However, I almost always find myself feeling insulted within a comment or two, and others clearly feel I'm being insulting too. Perhaps the limitations of comments don't help - after all, being "short" and "abrupt" usually means being offensive. And sure enough, long in-comment discussions are discouraged, and these things very often lead to long, somewhat heated in-comment discussions.
I was a little surprised to not be able to find any advice in the FAQ or on meta - maybe I'm just not looking hard enough.
So - what advice can people offer? And should there be something in the FAQ?
Or should this just be a common sense thing? - if so, I'm probably doomed :-(
