I have a paranoid delusional theory about the United Healthcare CEO. It stems from cognitive biases such as "jumping to conclusions," so take it with a grain of salt, but I like to share my thoughts so here we go.
The killer is legit, American citizen, denied healthcare etc.
However, the initial online reaction to him was almost entirely fabricated by internet trolls seeking to divide the United States.
But they struck a chord, and now many Americans are on board with a violent revolution. This is exactly what the trolls want.
Would a violent revolution harm us more than it helps us? It's hard to say. But if internet trolls are pushing us into it, they will be prepared to sabotage it at every step to ensure the worst possible outcome for everyone.
