Who says 6RD is bad? 6RD and RFC 5969 which documents it, are both GOOD
things because they will accelerate the switch to IPv6. The discussions
are about ARIN policies which SUPPORT and FACILITATE 6RD. But the fact is
that 6RD is a temporary stopgap measure. That is not bad, that is just the
facts. And we should be clear that we are only supporting and facilitating
6RD as a means to an end, namely native IPv6.

This is not really an ARIN problem. Network operators have to pick and choose
their technology based on their needs and understanding. In any case, ARIN is
not involved with 6to4, but ARIN can play a role in facilitating 6RD.

ARIN is not the Architectural Regulator of Internet Networks. It is the 
American Registry of Internet Numbers. ARIN does not run the Internet, not even
in the USA. ARIN does not specify the Internet's architecture and design.
