As do I. Which is why I attended the panels described.
Again, yes, no disagreement here.
But I have been “talking to POC in the fandom community” for decades now — not just panel discussions, but late-night room-party conversations, social conversations at the bar, and personal discussions with my POC friends and lovers who are SF writers and/or fans.
And my summary above is what I’ve learned by doing that.
But my initial point wasn’t about whether that fandom is or isn’t welcoming to POC, or whether it’s as correctly egalitarian as it ought to be.
My point was that,. for whatever reason, POC don’t seem to flock to lit-SF fandom, and lit-SF fandom is far and away the most fertile source of new SF/F writers.
So the naive simplifying assumption that the fraction of short-fiction sf/f submitted by POC is the same as the fraction in the general population is… well, unsupported by any evidence, at best.
Frankly, it looks like either laziness and ignorance of the subject, or deliberate statistical manipulation aimed at making things look worse than they are.
NB: I am not, not, NOT claiming that SF fandom is some perfectly egalitarian utopia.
I’m just saying that there’s a major flawed assumption about submissions in that post — and that assumption underlies all the subsequent mathematics.
There’s no evidence to support that assumption, and plenty to contradict it.
And flawed assumptions make for flawed and unreliable conclusions.
