Be educated

I dunno. I feel like if history was taught more accurately, ppl would be better able to grapple with being non-important. Since history is taught badly, certain types of ppl think their ancestors or group did more by themselves than they did. They can't reconcile why their lives aren't awesome. Similarly if basic logic and certain historic conspiracies that fell apart were thoroughly explained, ppl would have a better sense of what humans can and can't do (hint: we're terrible at the large scale conspiracies anti-vaxxers, anti-science and anti-government ppl see everywhere.)

People honestly have nothing better to live for so they go all in on it. Though I bet theres a lot of trolls

I feel they're kind of like the emos and hipsters of yore. They do it to be edgy and different and rebel against the status quo. That, or brain damage
