Now that we collectively know too much about the harms perpetrated by our government, we have also lost that sense of unity and shared values and purpose.
Access to information isn't bad, but we also need to remember that we're all part of the same team.
Increasingly, partisans on both sides of the political and social aisle don't actually care about the opposing side. They just want to win.
And this is why countries like Russia, China, and Iran have been so successful at weaponizing disinformation - it's being used by partisans on both sides to undermine the other, leading to chaos.
There are various different definitions of "communitarianism" but the idealized American Town Hall model of direct democracy is a direct example of communitarianism at the local level.
Political Scientists and Philosophers (all of whom are mainstream btw) like Michael Walzer, Robert Putnam, Charles Taylor, and Michael Sandel all touch on a light form of communitarianism that directly connects with Democracy.
Individuals absolutely should have autonomy to choose what they wish to do, but not if it has an impact on the rest of society.
Fundamentally, some amount of regulation (either via social norms or via actual laws) is needed, yet we as individuals will continue to fight each other while ignoring the core fact that we are all on the same team.
I strongly disagree with Wang and Xi, but on this part I am in agreement - individualism has gone too far in America (both economically and socially), and we need to return to our communitarian roots.
