I don't see it as inconsistent. What I see, & I don't wish to speak for others, so I'll just put it how I personally feel, is: When the author comes out long after the work has been released, as opposed to within the actual text/movie, & says "oh, yeah, years ago, when I wrote that, I totally meant X", it's pretty meaningless.
Like "Dumbledore is gay" when there's no indication in the text, or even mentioned at the time. Or, "Han's a hero, he wouldn't shoot first!", or "Hermione could be black". If that was actually the intent, they'd have written it into the text, or at least mentioned it at the time of publication. When the author comes out years later & retcons their "intent", that they, the author of the work, didn't include in their original work, it's hard to take it seriously, no matter how admirable the retcon might be. It's, to reference a term used upthread, "virtue signaling".
Either they were afraid to actually write it into their work originally, or they've changed their mind since they wrote it, trying to retro-fit their current views into their previous work. Neither explanation is to be applauded. It's more a "have your cake & eat it, too" thing.
