I’m a Universalist. It is all the same thing at different phases of matter at various temperatures and pressures combined with the gravity to hold onto various materials. Keep stacking Earths over and over and you will eventually get a gas giant then a star then a black hole.
What I will never support is the stupidity of defining any object by external criteria. If a gravitationally bound world is acted upon in a way that shifts its orbit, the object cannot be redefined. This is a definition of a state, not an object. Planet, as defined by the IAU is not a noun. Such is what I expect when a highschool teacher wrote a definition instead of actual planetary scientists. I suppose such draconian nonsense was intended to show the backwardness and medieval state of the science of astronomy.

You can hide behind fancy words but clearly this is just being simplistic
noun ?
I’m sorry if you didn’t get my lame joke over the fact that the universalist and simplistic definitions of planets give the same result in the comic
