Biological differences are real but lots of them can be changed by hormones. People caring about how they are categorised is universally central to a lot of people, this article illustrates that. I think ciswomen have the right to be upset about changes in language but transmen deserve no less rights for being a minority. How different ideas of how language should be used can be reconciled is not something I know the answer to, but denying the biological reality of changes experienced by people who are trans is discrimination. I don't think the complaints expressed by this writer are invalid, quite the opposite, but her support for gender criticals makes everything hypocritical.
