Here are my thoughts on this issue as a whole. I'm not talking about this specific case, but the whole non-binary, other-kin, genderfluid bullshit. It stems from a peaceful and comfortable life. People have nothing else to worry/think about, so they start with this crap to give their lives some excitement and meaning, and to feel like they're doing something and not just a spark in the universe. If we want this to change, the most effective way is to give them something to be concerned about, like famine or war. Why didn't this shit happen in the 30's and 40's? Cause anyone with a penis was sent to fight/die, and anyone with a vagina needed to come up with any means of supporting her family while the men were being slaughtered overseas. That's hard fucking life, and people had no time to think of idiotic bullshit like today.
So, the only way to restore order is to have another world war... Or we put up with these lunatics and live in peace, for the most part (excluding vans/trucks/planes of cultural enrichment).
