No it's not
It's just another way to tell lgbtq youth:
"Hay, we will do what you want and after that you're on your own, so don't come back for us whining about sui¢ide again."
Dumb atheists like Dawkins should have no say about gender or any reality period.
You want societies without religion then "you should" accept societies without any objective truth and that includes gender.. bit¢h
