You can't "lock" something that doesn't exist.

I don't see how making a thread trying to pick apart commonly accepted terminology is going to help the fact people are making fuss over this issue though

If that meaning is indeed a commonly accepted meaning for the word gender-lock, I should be able to look it up on google and see that meaning. But all search results point to using it for describing a class locked to one gender only in other MMOs. If you add the word "race" to your search, you will get FFXIV forum posts and articles regarding male Viera and Hrothgar.
