It has been over 14 years since the IAU passed its definition of what constitutes a planet, and we still get arguments (mostly rants) against that decision. For example, Where to submit, or ask to submit, a proposal for a redefinition of a planet to the IAU? The question in question was closed (including by me, as a doxing request).
These people are not asking for a rationale for the definition. These people appear to approach the issue from a point of irrationality and intransigence. Moreover, whether or not one likes the definition, there is nothing we can do about it.
