You know what's interesting about all those examples?
They're still literally all INDIVIDUALS and thus my point, which you quoted, stands exactly as I stated it originally.
Just as the fact that Orchis explicitly has a genocidal agenda means that any of its members - whether or not, if left to their own devices, they would individually seek genocidal actions towards mutants - are still explicitly okay with the overall approach Orchis takes being, y'know, genocidal.
And thus. My point. Which you quoted. Stands exactly as I stated it originally.
An organization declaring war on an entire people can not be reciprocated unless the people they're targeting then declare war on an entire people in turn. Mutants wanting Orchis destroyed is one thing, but mutants wanting HUMANITY completely destroyed, based on the actions or threat posed by Orchis, THAT is what would literally make them the equivalent of Orchis wanting MUTANTS completely destroyed, based on the actions or threat posed by the individual mutants you named, and others.
Are mutants talking about declaring war on humanity, based on Orchis' existence or actions?
No.
Ergo: false equivalency is false, and even your hypothetical about how it COULD be made to be an equivalent exchange is STILL a false equivalency, because the only true equivalency would require the existence of even a group of mutants plotting the extermination of humanity, and no such group exists in ANY of the books, at this time. And even if such a group WERE present in the books, the only actual equivalency would at that point STILL only be between THAT genocidal anti-human organization, and Orchis' genocidal anti-mutant organization.
The mutant amnesty deal only covered PAST actions. No matter what mutants think about those actions individually, they explicitly did NOT include amnesty for FUTURE actions. So mutants even 'being okay' with the actions of mutant villains in the past, in order to allow for the universal inclusion deal that was the entire BASIS of the Krakoan experiment....is NOT the same thing as saying that mutants as a whole would condone mass murder of humans moving FORWARD....and the same can not be said to be true of Orchis personnel in reverse. And as one of the three initial laws of Krakoa is literally kill no human, and even mutants who have in the past attempted genocide all explicitly agreed to it, you categorically can not pretend that the mutant amnesty deal is the same thing as X-Men saying we'd have no problem with any Krakoans trying to wipe out humanity at some point in the future....which again....exact opposite of what Orchis members tacitly agree to by signing up with that organization.
Unless every mutant character on Krakoa at some point gets on board with the idea that Krakoa wiping out humanity on mutants' behalf is something they'd actually be okay with, there is no scenario in which Orchis vs Krakoa is an equivalent moral conflict. None. Nada. Zip. Kaput. Zero.
