I'm guessing you've never been on TikTok. It's a pretty good news source and information disseminator. Your algorithm feeds you what you pick so if you linger on posts from physical therapists and psychologists about child development, that's what you learn about. If you linger on political posts highlighting our local and federal government's corruption, you get that.
I'm all for banning it (and all social media) for children, but if you think TikTok is all trash TV, you've been successfully propagandized.
