IMHO, a misapplication of the term "hoarding", which I interpreted as being 
a sarcastic comment, not an actual accusation.  (Michael: If I read that 
wrong, please let me know so I can flame you.)

Right.  One of the goals in IPv6 policy is minimizing routes in the DFZ, and 
it's easiest to do that if everyone (or nearly everyone) has the same size 
blocks because it's easy to filter deaggregates that way.  While a /32 is 
way, way too large for most LIRs, it's large enough that nearly all LIRs
will fit in it, it's a convenient number, and everyone can filter anything
longer than /32 (except in the PIv6 block, where it's /48) with impunity
unless they specifically want deaggregates.  Since we have absolutely no
clue how to route the half a billion /32s in 2000::/3, there is no reason to
give out longer prefixes -- and plenty of reasons not to.

I wouldn't use that term.  If you have the smallest allocation/assignment
that you need or that can be issued, you can't be "hoarding", IMHO.

I don't think anyone's faulting legacy folks for the inefficiencies of
classful assignments.  What I see them being faulted for is that now, when
VLSM and CIDR make giving back possible, many of them are choosing not to. 
(I'd say "most", but I don't think "most" have been asked yet and are likely 
unaware of the problem facing the RIRs soon.)  Some are knowingly hoarding 
address space in anticipation of financial gain, aka speculation, and opting 
out of the need-based system the community has endorsed and which gave them 
those oversize (due to inefficiency) assignments in the first place.

The "ridicule and harassment" is coming from a very small group of
unfortunately vocal people.  The rest of us are trying to be polite and
merely ask that legacy folks give back what they don't need (even using very 
liberal definitions of "need").  If we did a straw poll of folks favoring
carrots vs. sticks, I'm quite sure the former would outnumber the latter by
an overwhelming margin.

And, to be pragmatic, the fact that all v6 allocations are under RSA (as you 
mentioned) means that ARIN could "fix" the situation with blanket /32s in 
IPv6 if it ever became necessary, unlike the inability to "fix" legacy IPv4
assignments.  I hope that never comes to pass, and I don't see at present
how it could, but ARIN is covered just in case.
