One of my biggest pet peeves is that the term “gender,” once confined to the the world of linguistics, seems to be replacing ‘sex.”

Funny, because it seems that is used by people who generally are very “open” about sex (1st def), but want to be discreet when talking about which genitalia.
I believe strictly speaking, “gender” refers only to language format in those strange languages which haven’t advanced to purely neutral as English but insist on labelling different things as “male” or “female”.
