Pluto should be grandfathered into staying a planet. Who are we to say what or what is not a planet? Why America? Pluto doesn't belong to anyone. It's out there doing it's job and plus we can no longer show the Pluto episode from the Magic School Bus to our kids if Pluto is no longer a planet.
"If it looks like a duck, and quacks like a duck, we have at least to consider the possibility that we have a small aquatic bird of the family anatidae on our hands.'"
