i am familiar with okdoomer and i think it’s indicative of the sort of goofy goober shit most doomers have to work themselves up about to even get in the mindset in the first place, which is hyperfixate on anything which validates their priors and ignore the overwhelming body of evidence which contradicts or actively rejects their priors. even people on /r/collapse sometimes complain about how most of what the subreddit does is post poorly sourced suicide-bait and i think okdoomer is the tenuous but logical conclusion of that
in my mind, the resistance is just a common sense thing. active nihilism is dumb and brain poison. you will simply never do anything useful if your starting position is “this doesn’t matter and i don’t think there’s anything anyone can do to make it matter”–in any case this is a completely falsifiable and illogical position. a whole lot of shit does matter even on the margins. 2.9C of climate change is not an academic distinction versus 3C of climate change.
from a practical and crude standpoint, the conclusion of the position is you might as well kill yourself because it’ll never get better–but conspicuously, the vast majority of self-IDed doomers don’t do this and instead continue to do what amounts to malingering in a world they believe is going to eventually be characterized by resource wars, mass famine, and a climate that wants to kill them. that makes no real sense unless you think these are exaggerations, which i think many of them do actually recognize deep down.
from a personal standpoint, engaging in doomerism will just ruin all your relationships–nobody likes to hang around a complete downer.
