In which case you'll need to invent a new word, not tell people they're wrong to use a word the way it's long been used.

Telling people they're wrong to use a word in an old way is not very constructive, but language changes all the time, and when everybody starts using the words that way, then that's what they will mean.

The comment that started all this was:

> You and the earlier commenters are using the word “gender” when you mean “sex.”

Clearly not everybody is using the word that way.
