After all, a typical debrief in training isn't exactly a hug-fest...
Mine were... But I put that down to having been "debriefed" by Rock SNCO's during my Basic Gunner Course...
One has to be so politically correct these days.
Actually, one doesn't
have to be politically correct. However, so many people, (most of whom don't wish to have to be PC but are too scared not to be), will castigate you if you aren't that many don't have nerve, (or the time to defend themselves against the blind hatred that results from the noisy but stupid few), to go ahead and say what they mean... (I, of course, don't seem to suffer from that disability...

).
at least it wasn't 'text speak'!
I disagree. Text speak is a deliberate misspelling of the word for the purpose of brevity and to save money in some cases. Consistent misspelling when not for the purpose of brevity is ignorance and does need to be pointed out. In either case, other than the usual abbreviations, a forum such as this is not the place for brevity or text speak. In your own way you just lowered the standards yourself by "allowing" misspelling on the basis that it was not annoying to you, (and others - myself included), rather than condemning both as being inappropriate to the venue.
do all he can to correct his shortfalls, whether he perceives them now or not
Unfortunately, the reality of youth is that they have no shortfalls. I clearly recall being a mental giant, with a physique that was the envy of the world, Fabio-like good looks and simply oozing charm... (and that was just last week... I was worse when I was young...

). It's also easier to pretend you are learning "vital skills" on that Playstation than to do silly things like study. Come on now, who needs maths to fly? Your instruments tell you all you need to know...
Do people understand at school that eventually semi-literacy will not be acceptable for advancement?
The problem you are missing in that statement is that it is the teachers and the school administrators that are failing to see this... The students will only raise themselves to the standards those above them expect of them.
PS Rainboe: I'm not picking on you... Your post just gave me some "rant material"...
