Wait, why do you consider learning about things initially through social media a bad thing?
Sure there is a ton of nonsense and outright lies out there, but social media is also unarguably a massive source of education for people on a dizzying array of topics. Look at how silly but genuine ADHD tiktok or instagram accounts have massively raised awareness about ADHD for the better as only one example. Look at /r/ADHD as a huge source of good information and discussion for people with ADHD as another. The existence of social media has irrevocably raised the voices of the oppressed in a way TV and newspapers aren’t really interested in doing except for the odd anomaly that gets through the filter of the rich.
