My read is that post is not arguing what you think (that it's caused by freedom to present how they feel and that it's a representative population) but instead that it's caused by a selection effect. But this argument is implied so I see why you mistook it.
That's correct. I suspect there's a selection effect where people who struggle with these challenges in their lives find comfort in a space where they can present as the person they want to be without constantly being questioned, attacked, or otherwise made uncomfortable. And that's not because this industry is more enlightened, but because it's much easier to contribute and participate only with an online persona that can be divorced from your physical characteristics.
I hope it's clear that I am not trying to speak authoritatively and that this is more or less a total guess on my part based on some pretty superficial analysis.
