Since this is at the top of active, take notes on how the alt-right radicalizes casuals. We could stand to learn a thing or two on how they reached casual right-wingers to help us with radicalizing liberals. :P
Being a doomer is accepting it and not trying to improve the material conditions of others in the meantime. It’s the “we’re all fucked and there is no point in trying if society will just collapse in on itself anyway” attitude that makes someone a doomer, not being prepared for that inevitable societal collapse. We all have a moral imperative to reduce suffering where possible and recognizing that it will collapse and fuck a LOT of people in the process isn’t inherently doomer. Our actions are what separate the doomers from the bloomers. Roll over or fight back.
