Something like a constitution, a set of shared base beliefs that allow people to have the same base language to engage in a productive discussion, otherwise it turns into a mob discussing whether the vaccines work or not and no conclusion is reached. In a controlled environment or in a parliament, it's possible to have these wide-view from-first-principles discussions of society. Not in mainstream media and certainly not online, as you've probably seen in any unmoderated forum.
