For one thing, the extent to which parallel timelines are interrelated in-universe is debatable at best, and it doesn't put their temporally corresponding events in chronological sequence with one another.
Here again you have chosen your own specific restrictions as to what you call a "chronological sequence" that others may not necessarily observe. Another reasonable view is one inclusive of
all the infinite parallel timelines/realities as subsets of a greater whole.
I'll take a page from Doc Brown and draw you a picture:
_ _ 2233_ _ _ _ _ _ _ _ _ _2266_ _ _
\ _ _ _ _ _ _2259 _ _ _
Despite the divergence of timelines, there can still be seen to be an
overall chronology in play, not limited to one particular timeline. Just because the specific events of one do not directly lead to the specific events occurring in the other, that doesn't mean 2259 in one doesn't precede 2266 in the other. In that larger sense there could still be perceived to be a chronological flow and order to things, even if they are happening in different parallel timelines, different "locations" so to speak. It's certainly not the
only possible way to look at it, but can you really claim it's "incorrect" relative to yours?
Also, whatever "interrelated from an out-of-universe standpoint" is supposed to mean, it surely doesn't have anything to do with in-universe continuity.
I think you overestimate the importance that in-universe continuity may hold for many audience members. To a lot of people all this alternate-timeline-parallel-reality-mumbo-jumbo simply may not matter. When some see Pine and Quinto's Kirk and Spock having adventures, all that really matters to them is that these are younger versions of Shatner and Nimoy's classic characters. What's seen of them can naturally be related to and cause us to infer things about what's been seen before, in spite of the fact that we're technically watching alternate versions. There's a broader sense of "continuity" there that transcends the in-universe details, the kind of details which may be more or less significant to some than to others.
And even those mindful of such technicalities can't help but see the deliberate parallels in things like the reversal of
Wrath Of Khan's climax in
Into Darkness. These films intentionally play on a certain degree of familiarity with what's come before, expanding on and adding new context to it. Not everyone
perceives it as erasing or overwriting or happening wholly separately and independently of that other "future," even if that
is what's suggested to be happening in-story. This can be true even of many "harder" reboots.
None of this means
you have to perceive or describe things any differently than you do, but at least try to be sensible and open-minded enough to recognize that your view is not the only conceivable one. Responses to art are individual and subjective and varied; it's not about absolutes. To me you seem to be arguing from too narrow a perspective, wanting there to be a definite "right" or "wrong" reaction and according description. What you see as the
misuse of these terms, I see as merely a
different use, reflective of a different interpretation of their meaning and/or a different perception of the art being described.
Completely relevant. The hypothetical example was nonsense as it was based in a false analogy.
Okay then, don't like that analogy?
Pick your own, and go take up this argument with an English professor. I'm done.
