Everybody's Entitled To Their Own Opinion
And there certainly are enough dynamicists who agree with you to have pushed the current definition through in the absence of a sizable number of planetary scientists. Pluto is an icy dwarf. There are also gas giants and terrestrial planets. I don't mind pluto being called a dwarf planet or an icy dwarf based on a clear logical definition. It is clearly smaller and of different composition than terrestrial planets. I do mind a silly stupid definition for a planet whose primary goal was to demote pluto rather than to make a sensible definition for a planet. The definition of a planet should not depend on where it is located period based on the fact that we now know planets migrate.
