Have already decided that when confronted by somebody dictating their pronouns, I will respond this way:
“Why should I use pronouns for you when nouns and modified nouns are more accurate, like ‘snowflake’ and ‘gender denier’?”
Not gender.
SEX.
Gender is a language term. If you think it is "too crude" Queen Victoria used the word sex with out a single blush.
Gender is a term promoted by child rapist John Money.
