[LEAPSECS] The definition of a day

Several recent emails by those who want to end leap seconds are saying
that sometimes the other side just ignores their arguments as if they
had never been made, and that various resolutions are greatly
misquoted.

There is a presentation on the USNO web pages that says it has
referenced every argument made by those who want to keep leap seconds.
Do people who want to keep leap seconds claim that this presentation
and others like it have not even acknowledged the very existence of
their concerns?  This is different from saying that their opinions are
disagreed with, considered not important, or even ridiculed.
