@Frank Apisa,
As discussed, for me to say that "angry personal exchanges..." are par for the course and would come with neither surprise nor disappointment on the part of an aware reader, is not to so say that I am "so blasé about them" as you assert, but that I consider that we are mostly animistic in nature with a higher functioning veneer, thus it may not be reasonable to expect more than that in our present state.
Again contrary to your assertion, I am not blasé about a common human behavior that I consider to be based on our mostly animistic nature, however I do consider it rather an inevitability at this point. Expanding on that concept, Man's progeny may well be artificial intelligence, and/or the cybernetic integration of man-machine. In that case all bets are off as to expected behavioral characteristics (except perhaps the drive to survive).
As such, the question to me becomes: is there merited information that I find to be of interest in "angry personal exchanges..."? I would respond: it's easy enough for me to recognize those types of posts (and the posters most likely to post them) and skip over them so perhaps I'm just effective at real-time filtering. From that Frank, it should be relatively easy to infer that I do not generally find merited information of interest in "angry personal exchanges...".
Expected? Yes.
Predicable? Yes.
An inherent characteristic of our mostly animistic nature? Yes.
Worthy of study and analysis in a disciplined scientific manner so as to learn more about human behavior. Yes.
