You say that as if you know that for a fact, I've seen them over + over again (anecdote, but still), as well as many other such passive-aggressive responses. I often do take action on them, however the prevalence makes me think that not enough is done about the standard developer issue of people not knowing how to behave civilly to one another.
Frustrating to be so downvoted for raising something that is so rotten by the way, presumably it's ok to talk down to somebody simply because you feel they haven't put in enough effort in asking a question?
Or perhaps it was the language? That stems from being frustrated with the nasty culture that seems to be seeping in to so many corners of our development communities.
