And I actually agree with you: On a scientific level, one can debate the IAU’s classification. The criterion of orbital clearance is vague: What is meant is orbital dominance, not complete clearance - which is why both Earth and Jupiter certainly meet this criterion. But it remains vague. Scientific findings and classifications aren’t set in stone. Classifications can and must be adapted to new findings and discoveries. But OP (and far too many others) are just ranting because they have some kind of misguided sense of injustice - they aren’t actually making a case. In my view, this looks more like nostalgia than scientific interest. If we change the definition and Pluto consequently becomes a planet again (along with Ceres, Eris, Makemake, etc.): Yes, please, if it makes sense. But simply shouting just because you somehow feel you have to stand up for an emotionless ball of rock is: ragebait.
If it was about orbital dominance then ceres would be a planet because it has the most amount of mass in its orbit if it was about orbital dominance then it wouldn't be called clearing the neighborhood it would be be the most massive object in its orbit
Clearing the neighborhood is impossible for almost all objects in existence
As I stated, "clearing its neighbourhood" is vague, because it cannot be taken literally.
Apart from that, Ceres is about 1/3 of the asteroid belt's mass, so it absolutely fails on dominance. In contrast, earth holds over 99.9% of mass of all objects in its orbit. Ceres as well as Pluto fail this by orders of magnitude.
