Well, I can't understand illogic either, but it's not too hard to obtain data about the issue and make rational decisions about IPv6 vs. IPv4 networking.  :-)

Quoting from page 5:

"* 0.238% of users have useful IPv6 connectivity (and prefer IPv6)
 * 0.09% of users have broken IPv6 connectivity
   That is, adding an AAAA record will make these users unable to view your site"

Approximately 2 or 3 users per thousand prefer IPv6, and approximately 38% of these IPv6 users have broken connectivity, as of [2008].
