While I disagree that “the publishers went woke” is a salient reason (or even true in any real sense), I give the essay props for resisting the urge to reduce a very complicated problem down to a single causal factor.
As opposed, for example, to Richard Morgan's A Land Fit for Heroes. Where the main character is gay. He was persecuted for being gay. There are gay sex scenes.
However this is not what the book is about. Stuff is happening in that series. He's the hero of a decent story.
But then I'm talking about a fantasy series so it's not "literature" :)
This doesn't seem to be "wokeness" (whatever that means) so much as "shallow writing pandering to an editor somewhere who is obsessed with race but has no education to grapple with it".
