I am fine with labels, just don't expect me to care about them. It's not that I don't like that they help some folks, I simply don't care enough about any of them to be bothered.
My least favorite is 'preferred pronoun'. Son, I won't even remember your first name in an hor, there is no way I am remembering your pronoun. There is a reason we iuse pronouns, and its because they are readily accessible and guessable.
