Christ I cannot believe I'm going to get into this again, so I'm going to keep it short and simple.
Everything already has very specific labels. Society just doesn't use them because they're seen as the default. A "regular dude" is a cis-, heterosexual-exclusive, white male who is interested in blond, 21-35 women of a certain size and from a certain background.
Expressly defining these things is just a way to make it easier to determine who you are. Nobody is going to be asked to be called a "genderqueer bicurious pansexual", that's just what they are, just like a "regular dude" won't be asked to be called a "cis hetero male". They have preferences of he', her' 'they', or something else.
And third, why does it matter what someone wants to be called? How does it affect your life? Do you come in contact with people so often that would prefer to be called 'they' that it negatively affects your life with trying to figure out what to say?
