Silently judging your winter fashion choices.
OK, the riled-ness begins. I was impatient, expecting instantaneous fury. It can take a moment. So:
Some commenters defend teacher overshare on the basis of students who make mistakes deserving to be shamed. Also: students who make the kinds of mistakes that get shared are (apparently? huh?) the ones who don't care about school... which somehow translates to, who wouldn't care about being insulted by their teachers. Never mind how many of these mistakes aren't actual errors having to do with course-related material that's being examined, but random things/terms students themselves bring up without quite understanding. No! say these commenters (sometimes in all-caps). Being mocked by your teachers builds character!
More broadly, they're saying that to be hurt when insulted is to show weakness. If this were just a few commenters in one place once, whatever, but this is, in a sense, true of much online activity, from Gawker (well, the old Gawker) to the Petey comments here. The what-was-once-called-blogosphere seems split (somewhat but not entirely along gender lines) between hyper-earnestness and a kind of snark absolutism, where the greatest good is showing that one's feathers can't be ruffled. (Haz a sad, tiny violins, etc.)
It seems as though it should be possible to say that gratuitous hurt shouldn't be inflicted, without this in any way contradicting additional advice on what to do if you find that, say, your teacher has mocked you on Facebook. Yes, as life advice, 'choose your battles' is a classic, as is 'never let them see you sweat.' Unless you're going to go the full-on Outrage approach and all-out flip a snark conversation into an earnestness one, whatever it is, you have to laugh it off. (Are there any more clichés I might summon to address this?) Decompensation is generally a bad idea. That doesn't mean the initial nastiness was justified.
What strikes me in this case is that it's just so obvious nothing positive comes of knowing your teacher is laughing at you. Do you, the naive 18-year-old, suddenly become a well-read, world-weary 45-year-old? We can have a reasonable conversation about a certain amount of setbacks in youth - those early days of finding one's own friends, and the quasi-bullying that goes with that life stage - building character. Or about whether whichever newfangled whosawhatsit (grade inflation, hand-holding, the proverbial everyone-gets-a-medal) is perhaps detrimental to whichever pedagogical aims. There are times when the hazzing of a sad serves some larger purpose. But what aim is addressed by teachers acting unprofessionally?
