It seems like some of the confusion here stems from differing knowledge of how iNat implements the usage of common names. It could be useful to review that info here:

Also Tony made a nice tutorial of how some common name functions work here:

The original question was about designating new common names for species on iNat, so let’s try to keep the conversation focused there. There are several other threads that deal with common names that may be offensive, so if you are interested in discussing that, please direct the conversation there. If there’s a particular thread of interest, I’m happy to move posts from this one to there to keep the conversation focused.
