Note: I realized that I use "however" a lot. It actually just means that it is a counter to counter.
Also I may forget a thing or two, so don't hesitate to tell me if you see such thing.
On the downgrade side
-The argument about Taiji being 1-A is that since it created everything + can rewrite it and that their users are stated to be disconnected from existence/laws, it means that it holds a 1-A transcendance with absolutely every single thing in the world, including dimensions, time, etc... Something which isn't actually stated and is instead pure deduction.
However, this notion is contradicted by a lot of things:
-Akuro, a god, is called higher dimensional in an explanation about the nature of higher dimensions, even using the same terminology as others instances (also denying this feat as wrong/unknowledgeable/metaphorical/etc... is denying the only proof of dimensions being higher infinities we use so far).
The opposition answered this by saying that it was one of the many metaphor Shinza used.
However in that case it is explaining why Akuro couldn't be harmed and gave clear explanation regarding the fact that he was of a higher dimension, using the terminology K3 uses for them.
-3 Gods' laws were blocked by Madara's dimensional barriers, which use the aforementionned terminology + are already accepted as higher dimensional
Opposition answered by stating that Yakou weakened them, using him calling Morei's true name as a proof or saying that they weren't actual higher dimensions.
However Morei's scenes are either another fight or after the scene given, making them unrelated.
While them not being actual higher D is contradicted by them using the exact same terminology as the ones above + being already accepted as such.
Another argument is that since Yakou had Taiji, it means that the dimensions were being boosted by said Taiji.
The counter to this one is that Yakou's special thing with his Mukei is that he CAN'T change things, only summon them. So no boost here.
Not to mention that the scan used just say "it uses more than last time". But he like... already got his Taiji value uped last time too. Definitely nothing changing.
-Mibu slash was revealed to be a higher dimensional thing, which can even cut Tenmas
Was argued by other side to not be litteral, but it is a clear explanation/revelation of the true nature of the distorsion, and it being called higher dimensional right before being said to be able to harm Tenma is
-This one is very minor, but only those with godhood can understand complex geometric space, which is what prevent others from reaching Taiji and all
Opposition answered that it didn't mean Taiji was limited to this. It isn't wrong, since it is just a supporting evidence.
-The Throne's dimension is one among many in Paradise Lost, with others regular higher dimensions being a pathway to it (despite 1-A being unreachable no matter how much higher D are stacked up).
-The Twilight Beach is a world of frozen time, despite Gods/Singularity/Throne/etc... not being supposed to be reached by any form of concept according to the other side.
Opposition said that it was wrong because it was said that this world lacked the concept of time. Which is actually a misread, because it only stated that it lacked the flow of time. Since time is, not flowing.
Statements of Throne lacking the concept of time was also used, and it is legit to an extent, since it refers to it not caring about Merc law shenanigans. However same law is affecting everyone.
And statements of transcendance over time, which are pretty vague and from the english version (which added some of these statements despite not existing in the original).
-Mercurius revolutionning the world by "breaking some concepts" and implanting the idea of Multiverse is considered as a change so big it makes him unable to use the laws of his predecessors because of a lack in compatibility. Which wouldn't happen if they weren't affected by any changes done to it.
Opposition argument is that it talks about messing with the Throne system, making it unrelated to the world.
However it would show that the Throne was unable to apply an extension of the world (idea of Multiverse) by itself, despite being supposed to also be above every single extension of it.
-If it was inherently superior, then things like Briah, which are mere downscaled emanation, would make the user a fulll 1-A guy.
Opposition answered that we accept Briah as 1-A hax. Which is true but not what the other side meant. The argument here is that they should be full 1-A guy and not just have their imposition being 1-A. Although this one isn't too important
As such, downgrade side think that something like 1-B is more accurate than 1-A.
On the 1-A side
-Taiji is stated to be the origin of everything, concepts, laws, reality included.
Opposition argument is that it isn't 100%, since Pre-Throne Area lacked the influence of a Taiji and all.
However it doesn't matter much anyway, and Taiji is still the origin of what's in the current iteration of creation.
It doesn't mean 1-A transcendance over it.
-Taiji in philosophy is 1-A, and Taiji in Shinza is similar.
Opposition point is that we don't use real life philosophy stuff and all to upgrade a verse. Otherwise verses with Brahman would be 1-A.
-It is stated that Taiji fills all of creation and allows you to manipulate it, bend things to your law
Opposition argument is that it is law rewritting, nothing 1-A.
-It is said that Gods and coe transcend reality and are disconnected for the laws of the world. They are also stated to see it as a canvas on which they can paint.
Opposition is that you can do the same by merely having one level of transcendance, not a 1-A one.
Same for the canvas statement, which is either referring to the fact that their laws are overwritting stuff, which is considered as "painting" with their law.
And things about transcending "the picture" are used to say that they are higher dimensional beings, as shown with Akuro.
-Singularity is beyond creation, outside of laws and immune to its change.
Opposition argument is that the scan actually says that nothing that happen in Singularity will affect creation. Which prove disconnection, but no 1-A transcendance.
-1-A dimensions are a thing.
Except that 1-A for Shinza is based on the fact that they are supposed to be above every single extension of said dimensions. Obviously you can't both get a rating for not being touched by water when you get it splashed to your face several time in a week.
Another point of the opposition related to the whole stuff is that some points are based on 1-A being a given (mainly Yakou barriers somehow being 1-A because it "blocked a 1-A being"), which is a backward logic.
For these reasons, the person on this side think that 1-A should say
Either way
I would greatly recommand reading at very least one page (like really) or the major arguments of each , because while a summary is cool and all, it obviously isn't the same as a 4 pages thread.
I also didn't put the scans in this summary based on that idea, so there's that.
Just a recommandation tho, I can understand why one wouldn't want to read a big debate and all.
Everything's left to staff judgment now.
