I find this post strange because a large amount of articles didn't mention anything about sexism. It seemed more like a very angry minority of people, large amount of which were localized to twitter. A large majority of articles seemed to just be reporting on the news released from the fanfestival/interviews with Yoshida.
I would also say FF XIV has reached a certain level of mainstream appeal, maybe not the mass market appeal of WoW in it's hayday but it's certainly not a no name barely recognized MMO. The rest of your post just seems rather incendiary in general, while I disagree with using the term "vocal minority" as I feel it devalues an argument/group without really addressing that argument or groups debate. I do think this is still a very vocal minority who deeply care or would want the missing genders. Even if this is the most liked thread on the forum, these forums themselves are most likely a very very small part of the game's community as a whole.
I of course don't think this means they should be passed over and while I'd hope for them to be in development I don't think we'll get any definitive answer for some time. I don't think Rushing the dev team to answer when it's obvious they thought and discussed this issue at length before the release of the races is a very good or constructive tone to have as well.
This is just my personal opinion of course and I mean no offense by it.
