I think you are locking in on a semantic argument that is not Grant's
main focus.  When Grant states the carbon is not repairable, I think
Grant is talking mainly about the catastrophic failures that only
carbon can and does exhibit.  Like when the headtube breaks off from
the top tube and downtube.  Like when the fork legs completely break
off from the steertube.   Like when the frameset breaks into four
pieces.  I know that Calfee is a spectacular provider of carbon repair
services, and if I handed them the multiple pieces of a shattered
carbon frame and insisted on paying them to fix it, I bet they could
do it.  But would you actually get any of the above three failures
repaired?  I'd argue no.  Nobody has Calfee fix a shattered fork
(steel or carbon), but I bet Calfee could.  Nobody has Calfee lash a
headtube back onto a frame, but I bet they could.  Nobody has a 5
piece frame lashed back together, but Calfee could.  I think Grant is
labelling those repairs that no sensible person would ever do as 'not
repairable'.

I think the common ground for all of us is:

1.  We can agree that carbon frames sometimes shatter into 4 pieces
and that steel frames never shatter into 4 pieces.
2.  we could also agree that when a carbon frame shatters into 4
pieces it is not worth repairing.
3.  I think everyone can also agree that sometimes a stick goes into
your wheel and causes a cracked or broken carbon seatstay, that
probably would do nothing to your steel seatstay.  Such damage can
easily be and absolutely should be repaired in carbon.  If the steel
stay did get dented or bent, you would hold off fixing it until you
next wanted to overhaul it or paint it.

The thing that appears to scare Grant is the fact that voids inside
carbon are Gremlins that can cause it to fail without warning.  We can
all agree that voids in carbon are bad and we can all agree that they
are hard to inspect for because they are inside.  You have no idea
whether your new carbon frame has a void in it.  You trust, however,
that buy paying big big money to a top-notch supplier like Calfee or
Serotta that they are so good about designing their processes to make
voids vanishingly rare, that you can take the leap of faith that
uninspectable flaws are not there.  Grant and a lot of other people
can't or won't take that leap of faith, and instead choose steel,
which is inspectable for the flaws that can lead to failures.
Secondly, I think Grant and others are afraid of the surface impact
properties of carbon.  How do you know whether a pebble thrown up from
your front wheel at your downtube will lead to a crack that will grow
and lead to a catastrophic failure?  Grant knows and we all know that
95% or more of carbon frame riders do not regularly inspect their
frames for damage.  I rarely inspected mine.  If they did, how many
would find a flaw that should be taken to Calfee for repair (that
absolutely can be done)?  5% of them?  1% of them?  Even if it is 1%,
that's hundreds of frames that are carrying scary damage that on a
steel frame would not be scary.  Of those hundreds of frames, some
will shatter.  Will it be because of pebbles thrown up from the front
wheel?  Not directly.  Will it be a contributor?  Likely.  When frames
shatter, is serious injury much more likely?  Of course.

I think Grant's thinking and language are built on the tragedy that
out of the cycling community today, some of us will be paralyzed or
dead within 10 years, and that some small percentage of those injuries
or deaths would not have happened if none of us rode carbon.  That is
not a hard position to defend, and if you believe it strongly like
Grant does, it's actually kind of an outrage.  I believe that Grant
actually does lose sleep over thinking about the safety of us riding
'his bikes', and I think he loses sleep over the safety of cyclists
not riding 'his bikes' because he believes in cycling, and he believes
that this entire community should take care of one another.  Just like
there are plenty of 2nd Ammendment folks who 'bash' assault rifles,
Grant appears to believe that carbon fiber is bad for cycling as a
community and a movement.  I personally think he's a little rough with
his language, but I admire what I think his motives are.  I am certain
that money is not one of his motives.
