J. Michael Straczynski naming names in the afterword of The Last Dangerous Visions for…reasons? This seems wildly irresponsible and self-serving at the very least. Redacted are the name of eleven “diverse” writers.
I am guessing he must have felt the need to pre-emptively blame someone else for the lack of diversity in the anthology he edited (the final version of).
Can't really see that turning out very well for him.
OTOH, it seems to have turned out great for him. He hasn't lost gigs, and he clearly thinks he's right and doesn't need to listen to anyone's opinions. He seems to be doing just fine.
This is coming out today.
There are already plenty of people reacting negatively to it.
It usually takes at least 24 hours before anything like this reaches critical mass, and sometimes it dies down for a while.
I feel like this anthology is so niche-within-a-niche-within-a-niche that I can't see any meaningful blowback on those authors? Like, I don't know who's named there, but I remember some names JMS was looking to ask a few years ago, and... they all have better things to do.
Consequences in the sense of ruining a career, probably not.
In the sense of making himself someone few people in literary SFFH circles would want to work with is a possibility.
He is certainly not doing anything good for his own reputation.
