I kinda agree, but also want to offer a different perspective. I agree that the more specific labels are not efficient for communication in most cases, because nobody knows all of them and it’s easier to just say who you find attractive.

However, they can still be useful to discover more about yourself. As someone who’s aromantic and asexual I’ve found that many of the labels in the community caused me to ask myself the question “how do I feel about this”. Before finding “my” labels I just kinda felt like “nope” about anything related to relationships, but all the more specific labels and spectra have made it much more clear to me what I want and what I don’t want. They also provide a way for people to find others with the same experiences as them, which can feel incredibly validating.

These specific labels are a jargon for queer people, they make sense in their context, but are not useful when trying to communicate with most people from outside of the community.
