By whose standards? The United States has never been an ideologically cohesive nation outside some basic principles of representative democracy - and even those have been challenged at moments in our history. The moment you get beyond the basics of a unified military, postal service, weights and measures, and currency, you quickly get into the social issues that have plagued our cohesion since the founding of the nation. Is Uncle Tom's Cabin a seminal work in understanding US history, or subversive and dangerous? We can't even decide that as a nation at the moment, so "how much social media is good for our kids?" would be a very, very ugly discussion to have at a national level.
I don't have Tik Tok installed, my kids only get the "reruns" off YouTube, but frankly I find it a bit extremist that the US government wants to ban an app that looks to me like people doing funny dances in their living rooms.
