This has come up and has been remarked upon. It's more that said premises are considered to be irrelevant or side considerations by some of us, particularly to the sundering. If their world is less than perfect (but in relative terms I find them to be quite remarkable beings compared both to RL humans and the sundered), should they not strive to regain what they lost, even if that exact thing cannot be regained? After their star had nearly been desiccated and most of their people sacrificed to staunch it? As if many of the sundered would not desire and act towards the precise same thing? Note that the dispute between Venat and her faction and the remaining ancients was less to do with any of their imperfections, real or imagined, but more to do with the attitude she thought they should have to suffering, based on context she had and which they were not given and thus lacked.
Yes, much as ideology focused on discarding the past (except when it comes to using it caricatures of it to ideologically browbeat opponents), fixating on "brighter tomorrows", destroying all opposition to withering away the status quo and ushering in their own new glorious revolution, thriving on crises as pretexts for doing so, has very bad echoes to certain movements.
