I believe the title of this Wikipedia article is wrong. When we started replacing the word "sex" with "gender" a few years ago, we were careful to differentiate both uses. But a few years later some people started to feel like "gender" is the new politically-correct word for "sex". It is not: these two have very distinct uses, and using "gender" for connectors is ridiculous because - as far as we can tell - they have no social identity (yet!).
