Earlier quoted context omitted.
And how do you do that? Either you have some government agency able to quickly decide what is a "Russian bot" and censor it or you have a public deliberation process where evidence is required to be presented before censoring the Russian bot. The former is guaranteed to be abused to censor things that the government doesn't like and the latter is too slow to be of any effect.
You ... Work on aspects of your society that Russian bots can seize on? Fracture point propaganda campaigns only work because we let those issues fester.
And while I don't have any doubt in my mind that there are foreign entities working to exploit these fracture points, I am very skeptical that they are the main cause of problems here. We have seen such fracture points arise and cause political strife up to the point of civil wars many times throughout history without such foreign instigation.
