Yes, coddling mentally ill people influenced by DOTR ideology instead of trying to snap them back into some sense of balanced reality versus the ones they have created in their heads that override obvious facts is good for them. I'm sure that flip shooter from 4chan just needed to hear someone like LurkTrawl say, "There there, everything is actually as grimdark as in your accelerationsist fantasies. There's no good news, dear, ever. All hope is lost forever just like you think," would have helped him.
Just treat these people like the the left does troons. Mocking them for believing in things that are certifiably incorrect is bad because people with seemingly violent and authoritarian leaning world views are such fragile delicate creatures that can't take mockery. We should allow them to live in their burning hellscapes where everyone is against them in their minds whether it's true or not. Who are we to judge them, and what could possibly go wrong with radicalizing people with apserger's syndrome who think all hope is lost?
