“there are over 100 fucking names now and I’m too stupid to learn anything other than you”. No one is asking you to be psychic but instead to give their pronouns the same respect that they give your name. If you don’t know them it’s whatever but if you do and don’t use them on purpose you’re being intentionally disrespectful. Like if I know your name is Bob and call you Barbra on purpose that’s disrespectful.
