Exactly. There are many categories of planets, including but not limited to:
* Terrestrial planets
* Gas giants
* Ice giants
* Hot jupiters
* Superearths
And so forth. Why does the concept of another category, dwarfs, enrage people?
Really, the only categorization issue that I'm adamant about is that Pluto-Charon is called a binary. The Pluto-Charon barycentre is not inside Pluto, therefore Charon is not rotating around Pluto, the two are corotating around a common point of space between them. That's a binary.
I think it might be cultural. In Denmark and probably generally for Europe, I grew up with Pluto either never being mentioned as a planet or not said to be a real planet. I knew of Pluto from comic books and American media, so I always brought it up when we had any material on planets in school and Pluto was not mentioned. I was told over and over that Pluto was either not a real planet, or a planet but not like the others.
You can call dwarf planets, planets. Then we have growing number of planets in the solar systems many without proper names, that would be fun, but confusing, and they would still not be like the other planets.
