I agree with you in a very broad sense, but I also feel that stripping an issue of its complexity results in apathetic or impossible stances. Where do you even start to craft solutions when this is your understanding of the matter?
Yes, “they” might be fighting for absurd reasons but everyone does, to one extent or another. At some point there has to be a concerted effort to minimize casualties and suffering, and that effort usually comes hand in hand with picking a side - as long as your goal is a reduction in harm and violence, that side is often the weakest (in many senses). But pick any side for all I care, if your intentions are holistically sane.
This is inherently a political effort, one that necessitates impartiality in order to sway public opinion, political weight, budgets, etc. And so these weird “holier than thou” moments arise - yes, sometimes for the sole sake of claiming superiority, but more often than not because “impartial” action is necessary to move the issue forward.
Mind you I don’t agree with Wikipedia on this one, given its nature, but still - embrace the hypercomplexity and patterns and nuance will both emerge and you’ll have something to work with, at the risk of maybe realizing that often to play a part in reality is to pick a side, even if it’s somewhere on the spectrum between two insane positions.
