There is an independent association between problematic use of social media/internet and suicide attempts in young people. However, the direction of causality, if any, remains unclear. Further evaluation through longitudinal studies is needed.
Also your claim that "all evidence" points anything out is contradicted by the fact that "all evidence" is not contained within a single study, and the posted article points out that the evidence itself is in dispute.And there it is. I don't agree with you so I must be a shill or a disinfo agent. No, I'm not. I just disagree with you.
No one is actually arguing that things have to be proven beyond any doubt. Nor is anyone arguing that nothing at all can or should be done about the negative effects of social media exposure or the use of ALGORITHMS. There are ways to mitigate the harms of social media that don't involve the government's monopoly on violence.
What's being argued is that the arguments being made to justify having governments regulate and ban social media (and by extension, free speech on the web) haven't been justified by the science. "something must be done before it's too late" isn't a valid argument. It's the same "but what if there's a bomb" argument used to justify normalizing torture after 9/11, and the abusive policing of the Satanic panic before that, and literally every other ratcheting up of authoritarianism in the face of a moral panic.
But since I know you aren't willing or able to approach me in good faith on this topic, I'm done now. I apologize for triggering you with wrongthink.
