If "dealt with" means the same thing to you as does "skipped over without acknowledging," then yes, granted.
I'd rather not repeat answers and analysis that are already freely available in this thread. If you really did not catch the response, ask the question again, and I'll cut-and-paste the response.
Slingshotting is not an available option. Period.
Worship as we may at the altar of authorial intention, authors must still be held to account for what they accomplish, not just what they intended to accomplish. Indeed, we are nearing the old Intentional Fallacy (Wimsatt and Beardsley) if we presume that the author is the God with regard to the meaning and value of a work.
Again, I have already detailed how both universes are intermingled and how we cannot suppose tout court that slingshotting is not an option. All the evidence present to us in the text indicates that it is.
The (then-current) model upon which the idea was based is effectively obsolete,
Star Trek is not reality, it is fantasy. There is no "physics of red matter," there is no actual "warp mechanics" which underwrites the function of the engines of starships. If Star Trek shows us in a film that there is red matter which magically creates black holes from nail polish, then in that universe, this is the case. If Star Trek shows us Spock slingshotting around the sun to go back in the same timeline, then this is simply the case.
In short,
what fiction posits has greater standing, in term of internal consistency, than what the real-world allows. Our test in this case is coherence. If you want to get all real-world on Star Trek, then the whole universe falls apart. We cannot preferentially defend Star Trek as being real world in some aspects, but then arbitrarily beg off that standard when Trek is not real world. Real world physics has nothing to do with it.
and has been replaced (for purposes of this incarnation of Trek, at the very least) with a different model - one which does not allow closed-loop time travel. In practical terms, that mode of time travel never existed.
In which case,
The City on the Edge of Forever
never existed, Assignment: Earth
never existed,
The Naked Time
never existed,
Tomorrow is Yesterday
never existed,
All our Yesterdays
never existed, and
Star Trek IV
never existed.
And it isn't just this. What else never existed? Let's see...

Indeed, it appears that the Prime Universe never existed! And I thought I was assured that it was still "there" and still "real." Now I find that Old Spock's history and Prime Trek history does not exist anymore. Perhaps it wasn't Old Spock who came through that black hole after all? It is rather, Old Spock lite, with only those historical details that uncomplicate the reality of nu-Trek. So much for the soft-reboot, this is more like getting the boot.
To insist that it still does exist is to wilfully ignore The Way Things Are Now (according to the guys who are telling the stories).
What matters more than the confabulations and apologias of the guys who write the story are the details of the stories they actually tell.
If you're interested in participating in discussion, then you're welcome to do so. However, the recurrent cataloguing of fallacies in which you've been engaging has the effect, more and more, of making it look as if this really is the "gotcha" topic you've insisted it is not.
There is nothing about the topic which serves as a trap forcing my opponents to use fallacious arguments.
It's not playing "Gotcha" when Sarah Palin cannot answer obvious straightforward questions about national policy. Likewise, it's not playing gotcha, when the opposition hastily reaches for bad reasons in response to questions.
If the responses you're getting don't fit the answers you had already written on your checklist, it does not automatically render them invalid or fallacious
Of course not. Rather it is the fallacious nature of the arguments themselves which makes them fallacious.
It's not that I object to an
Ad Hominem because I'd rather hear agreement, but because an
Ad Hominem is so often a weak argument.
