If a maintainer closes a bug, and after a single round of explanation,
still does not agree with reopening the bug, the bug should stay
closed.

If you disagree with the maintainer, then your choices are to either
attempt to:

1) convince the maintainer that your viewpoint is correct, preferably
by submitting a patch which fixes the perceived problem, along with
rationale as to why the patch is correct.

2) attempt to convince the technical committee that the maintainer is
incorrect, and should be overridden. This necessitates a patch as
required for #1.
 
In neither case should you reopen bugs that a maintainer has
closed.[1] Continuing to do so will result in restricting your use of
control@bugs.debian.org.

1: It is of course acceptable to reopen a bug in cases when the
maintainer is likely to agree with you, but that is clearly not the
case here.
