Anytime bro...opinions are good; we all should learn from ppl
who correctly point out our flaws. 
Regarding your first point, about too much testosterone and too
little brain...I guess i didn't make this clear enuff, but in
previous posts, I suggested that it is not just simply volunteering
to get yourself through. It should include
recommendations/references from your BMT OC and Plt Cmdr based on
initiative and performance. I realize that most of these BMT
trainees might wanna go SISPEC or OCS, but there are others that
are just as capable, only that it doesn't show till later. Take for
example a unit needs to replenish its ranks with these types of
troops...which is later reflected in the postings we receive...wat
I'm saying we change is that it should not be a fixed/rigid system
of posting...change along the lines like..."a unit needs to fill
xxx number of specialized places and we are looking for volunteers.
People who wash out will be rotated back to their original
postings." No shame, no questions asked...
Second point. that unfortunately, we cannot really resolve...the
Navy SEALs has a high drop-out rate, and the SAS even higher. The
numbers of trainees do not have to be substantially higher, but
just a little more to compensate for losses due to injury or DOR
(Drop On Request). But there is a big difference between
volunteering and being posted...even if an individual washed out
from the course, he can at least say that he tried and had a taste
of wat it was like...
Third point, aahhh....isn't it the point in time when we ask
ourselves whether are we still boys or men? lol
Eventually, who makes the decision for us? Ourselves
or someone else? Remember, there's no consent form to sign
here...lol
jk...
Fourth point, correctly so. And I may not have made it clear, but
like you said and I totally agree, like many others here do, that
realistic training has to have certain safety parameters...although
I've gone through it before, head-dunking should be
banned...replace it with icy cold trickle showers....that should
keep the trainee awake and yet not breach TSR....
Fifth point, true...a death is still a death...many of us know from
training, that accidents/incidents do not respect rank, age or
status as NSF or Regular. However, I'm not suggesting that by being
an all-volunteer outfit, we ask for a free trip to Hell and
back...what I'm simply stating is that the individual who
volunteered for this knows what to expect of himself and what kind
of training is involved. On the other hand of cos', I refer back to
the 4th point in that there is a difference between being too
realistic and training safety....
SIxth point...There is already an existing "us" and "them"...you
don't see support companies or recce companies mixing with line
companies do you? Except for exercises of cos'...again with the
exception of BRC and battalion scouts...Most of us might know that
those from BRC, Snipers, etc, seldom wear the unit tee-shirt,
instead wearing our own tee-shirts procliaming the status of our
vocations. Second, some units allow their scouts to wear floppy
hats around the camp (except on guard duty) like a badge of honour.
Third, and this only applies to those that have carried it...the
carbine/sniper rifle is like a distinction of elitism within
units...I always liked to tease line troops about how compact it is
to have a carbine as compared to their M-16s...of cos'...its the
SAR-21 now. Last, scouts in particular (dunno about snipers, but
maybe you guys can fill me in on that) are always used in
unit-level training exercises to simulate enemy cdo attacks...why?
For reasons being that they are seen as the "elite" of
units...
My point? There is already a heightened sense of "us" and
"them"...elitism is more than just putting on a fancy tee-shirt or
wearing flop hats...it is earned through the hard way, therefore it
comes as a part of the 'territory' of being in a specialized
outfit...irregardless of volunteerism or otherwise. 
Good points you've got though...its just that I think such changes
are possible to achieve, albeit some modifications have to be
made...
