If some fans can't handle the idea that some folks don't see it as one consistent whole, to the point they have to shout down anyone in disagreement. Then their faith in the statements from TPTB aren't all that strong to begin with. They are desperately trying to hang on to something they can't even see.
I guess that cuts both ways.
It would be just as easy to state...
“If some fans can’t handle the idea that the curators and creators of these shows have decided that they ARE part of one consistent whole, to the point that they have to continuously shout down anyone who supports this line, then they are desperately trying to hang on to their own pedantic interpretation of a fictional universe and are unwilling to accept creative decisions that have been made in order to update the presentation for the broader viewing audience with contemporary expectations of what a sci-fi show should look like.”
No-one is suggesting that the Thought Police are at work here. Everyone is free to head-canon, retcon, re-canon whatever they want. What can not be denied, however, is the official line that the main series are all part of a single continuity.
It really doesn’t matter what I think or how strongly I may argue for or against it; that IS the official line — and it is what it is.
Inconsistency is pretty much a given in any long-running fictional universe, particularly where various different creative influences come and go. Sometimes it’s possible to create valid in-universe explanations for these glitches — but sometimes it’s just not worth the ridiculous intellectual gymnastics required to achieve this and it’s simpler to ditch the pedantry and accept this is an imperfect medium.
Even in a phenomenally detailed fictional universe with a *single* creative drive, and Tolkien might be a good example here, there are STILL revisions and inconsistencies that arise as the creator progressively develops and adapts characters, stories and situations. It’s certainly easier for them to create their own work-around for any inconsistency, what we might now call an internal retcon of their own universe. Tolkien undoubtedly did this quite frequently over the decades that he worked on Middle-earth and its histories. Sure, it would be possible to head-canon alternatives to his changes but ultimately that world was whatever he wanted it to be.
There are certainly series of novels I enjoy where the authors have done some weird WTF things with subsequent stories, and I would have wished that they hadn’t, but ultimately, even if I opt to kind of ignore or at least not dwell on those bits, if those stories impact what went before and what follows then I just have to roll with it.
It’s my take, and I accept that everyone’s view will be different, but I just kind of see Trek the same way.
