This is a very odd thing to say.
As a feminist, I would prefer gender-neutral pronouns in some situations (e.g. instead of the generic "he" used to refer to a human, as in "mankind", however, sometimes markers of sex are important (for example, you cannot possibly experience motherhood unless you are a woman).
I don't think I've ever met a woman who feels remotely comfortable with notions of "femininity", but most accept sex-based pronouns as far as they refer to biological sex. Certainly not as referring to gender!
Trans people who want to use the opposite pronoun to their biological sex do so because they believe they are of the opposite sex. So far, no evidence verifying these beliefs has been discovered despite scientists' efforts, so these remain beliefs.
People who wish to use different pronouns due to a belief in gender performativity are welcome to do so, but shouldn't be enforcing this on others or pretending, as you are here, that we align ourselves with their gender stereotyping or categorising simply because we accept sex-based pronouns as a linguistic default.
