The claim itself is invalid, due to Priano-guri posted it from name of ARC, and she is a de-facto CEO of an executor corporation of the alliance. Her decisions are policies of the corporation and thus the alliance, unless it is some sort of deep personal issue, and even in that I’d say it will be tied to Alliance policy/politics.
I strongly recommend studying whom are you joining to avoid fighting wars that are not yours. The History explains the Present and defines the Future.
As I have already mentioned in discussion of Lumen, it’s basically not about what Empires or you and me think about ARC, but about what ARC has done against the Empires. When you do something hostile to an entity or person, it’s unlikely they will consider you a friend or ally, isn’t it so?
The basis of every belief shall be a factual data. The alliance you’re talking about was literally started by an outcast (ex-diplomat) of a traitorous alliance, who exposed herself as a slanderous, cowardly and dishonorable person, posting openly delusional lies and incapable of not just proving, but even standing for her words. Moreover, she expressed a hefty degree of irrational hostility when she was expected to behave as a diplomat.
That is most definitly not a person who could lead anything even remotely resembling a “force of good”, she suits more for leading an organization of villains from gallentean comics. And if you indeed fell for that being a “force of good”, then meet me in 4-4, I have a Carbon to sell you.
