So Imma try to just look at this from a complete neutral outside observer.
First and foremost, opening up with the controversial and SJW thing immediately hamstrings any position or argument you want to make cause its a pre-emptive attempt to discredit any criticism of your position. Also, remarking about 100 years from now, historically, youre more likely to see people say the opposite: That the Social Justice and gender identity politics of our current era are very barbaric and brutish, most likely due to the over arching narratives both sides provide, rather than talking nuance. And Make no mistake, nuance is not a part of the dialogue at this time in western societies discussion on sex and gender. Particularly since both sides have made erroneous claims about how the 'science is 100% settled' on the matter.
Next, a part of the request is made on the assertion that there is a large part of the base that is gender non-conforming. The question then is to ask how much of hte player population is truly this? On its face, from anecdotal evidence, there are far more Gender Conformist players than non. Of course, that in of itself doesnt say there isnt a sizable number of the non-conformist community, but it does beg the obvious question of how many players make up this section of the player base. I doubt you have any hard numbers, but if you do, you should share them. This also being stated that you are inflating your perception of non-conformist players by using LGBTQ FCs. Of those, most individuals who would fall into LGBTQ would be conformists. That is, they do have a set gender identity, regardless of sexuality.
As for the fantasia, that is a non-sequitur almost in regards to your position. The issue you face is being non conformist, and since the game only registers 2 sexes, no amount of phantasia is going to solve the dilemma you are in. Youre actively wasting your money swapping between the sexes in that fashion. Which btw, you havent actually clarified your position, per say. Are you looking for gender neutral terminology when being referred to (so no him/her, but they/them), or are you looking for options for physical characteristics in the character editor? What is it specifically you are looking for when it comes to being 'non-binary'.
Thats my two cents atleast. Clarity is definitely lacking on your part.
