The deal is the weird part where they made a specific point of and big deal out of the new classification not being a type of planet despite having the word planet in the name.

Gas giant planets, ice giant planets, rocky planets, dwarf planets.
I don’t see what the big deal is.

The “big” deal is that a ton of celestial bodies of comparable size to pluto would have to be considered either as planets or as general debris. Finding a clear definition which would include pluto as a planet and not include other stuff would be very impractical and possibly nearly impossible.
But the biggest fuck up was to name a non-planet a “dwarf planet”.

Sounds like just another kind of planet to me.

Sure, people have taken the matter way too personal. That’s mostly people who have a nostalgic relationship to their childhood classes about “the 9 planets”.
As I’ve read, they made the definition in the particular way to remove gray areas of inaccurate meassurements. A celestial body shouldn’t be wrongly classified due to being a few kilometres larger than some limit, then be reclassified later due to better meassurements. Planets need to be somewhat spherical, orbit a star and clear their orbit from significant debris. They made a great system which doesn’t leave big gray areas. A planet is defined in a well thought out way by people way smarter than me.
And then they go and call the non-planets “dwarf planets”.

I’ve heard some push to just call them all “Worlds.” Planets, moons, asteroids, etc. and all, which is also fine by me.
