See, you lost me before with subjective reality and dropping useful nomenclature tools but, I do have to agree a lot with you on the utilitarianism and ethics of choice.

My allegiance to humanity (and any potential non-human sentience) is the most important part of my ideals. Critical analysis is also vital to choose the action most beneficial (without falling into the “ends justify the means” trap frequently seen in M-Ls). Inaction IS absolutely an action. In cases like the US elections, the data show that inaction and anti-electoralism have the same net result as supporting fascists.

The system in place offers two outcomes: a neoliberal + moderate + center-left party or a facist + theofascist party. While (neo)libs almost always ally with fascists over leftists every chance they get, they are objectively less likely to inflict the levels of human suffering that fascists will (and there is no concrete evidence supporting accelerationism). Any action or inaction is going to lead to one of these two in this system it is the fallacy of Denying the Correlative to suggest otherwise, based upon all available data. Anyone suggesting inaction or effort to support a spoiler to harm the chances of the neoliberal party is just saying that their personal moral high-ground and ideology is more important than the lives of Palestinians, Iranians, Jordanians, minorities in the West, other leftists, LGBTQ+ people, and humanity at large that would be harmed under a theofascist regime. All possible outcomes include continuation of ongoing genocide, the neoliberals might apply pressure to halt it, the theofascists would accelerate it and have verbalized the desire to bring a nuclear apocalypse to fulfill their doomsday cult prophecy.
