I, for one, am not wedded to nine planets. Or eight. Or fourteen, for that matter....
Fair enough. My mistake. Most people who whine about Pluto in the terms you used want to go back to 9 planets, and only 9, because "tradition".
I'd prefer to create a, admittedly still arbitrary, broad definition of planet as "any natural object that is above [a certain size**], and is not a star or stellar remnant." So brown dwarves, but not white. The Moon is a planet, as is Titan and the Galilean moons. Pluto is a planet, but so is Charon. And Ceres - as well as hundreds, possibly thousands of KBO/Oort-objects. Plus exo-planets, free-flying planets, etc.
People could then create official and ad-hoc sub-categories of these "planets". "Major moons". "Major Planets/Dwarf Planets". "Exo-Planets". And, for the whiners, "The Traditional Planets", ie, the magic 9.
[** "a certain size". I don't really care what that size is, whatever is useful to astronomers/planetologists. Anything smaller would be an "asteroid" (including small moons), down to another arbitrary limit where they become "meteoroids" (rocks and rubble), down to yet another arbitrary limit where they become "dust".]
