For those who don't know about the Attack Helicopter Story saga: Neon Yang and NK Jemisin harassed the writer Isabel Fall (a trans woman) for writing a queer mech story.
And harassment really dosen't do it justice becuase Fall was hospitalized for severe depression, and from what I've read has stopped their transition. Primarily becuase of intense gender disphoria brought on by Yang, Jemisin and their cretinous followers saying Fall must be a cis-man for writing this story. They didn't even read it, they just didn't like the title and invented a bizzare conspiracy theory that claimed Fall was a neo-nazi. Afterwards both of them gave a really shitty WhatApp apology and moved on with their lives, so much so that apparently Yang now has the gall to do this shit.
It's because the PMC struggle for relative social status leaves no room for morality, or even self-awareness. One's income and access to future opportunities (and ability to avoid falling into the working class) depends completely on controlling a share of a fixed-size pool of social capital, so social competition is ruthless, and there is no place for empathy or regrets.
