Never attribute to malice what can be described as incompetence. Doomers, in this regard, are simply incompetent.

However, the gap between the competent and the incompetent is actually manufactured, meaning incompetence isn't a moral failure. Also, inaction itself does have material impact, regardless of intent. Even then, inaction born of incompetence doesn't absolve anyone of accountability.

This matters because, at that point, the common reactionary behaviour towards doomerism, pessimism, inaction, especially IRL, is excommunication due to the habit of framing certain results of systemic conditioning as a moral failure.

Given that the decision to do something, even just a small thing, itself requires a certain degree of deconstruction effort, it makes you feel ahead of those who are stuck in their doomerism. But in reality, you are actually still where you are, and always shall be, as long as doomers are still around you, bothering you to the extent that you resort to assigning moral hierarchy among your fellow working-class folks.

For example, personally, as an Indonesian Muslim woman, I don't see imperial-core populations such as certain USians as malicious in their self-absorption, universalism, exceptionalism, and propensity to make every oppression and suffering an Olympic event. They are just limited in their vocabulary, which results in a political imagination that stretches only as far as their Orientalist and imperial upbringing and education allow. That does not mean it's not annoying the fuck out of me, nor does it mean it absolves them of accountability to resist imperialism from within, or absolves me of accountability to bridge the gap and continue building coalitions.

However, my awareness of mutual obligation or collective responsibility in liberation struggles and internationalism does not entitle anyone to endless grace and hand-holding; neither does it dictate how I conduct my end of those responsibilities, let alone absolve anyone of theirs.

But it should never alienate anyone, blur the boundaries between the personal and the political in harmful ways, hinder anyone's access to material support, assert any sort of hierarchy, or engage in any other behaviour common to carceral systems.

Otherwise, a movement ostensibly committed to collective liberation can end up reproducing the social hierarchies and punitive relationships it seeks to abolish. And the people least capable of performing political competence are often the first to be abandoned.

TL;DR: Emotional and contextual awareness are political skills.
