Since it's not in my interests to find one day an angry mob at my house, I'm tempted to give some advice regarding the "crowd management". The nation is like a bowl with liquid: the bowl is the borders that contain it and emotions is the force that drives the liquid particles. The exact equation describing this liquid doesn't matter much. What matters is that just like any liquid like substances contained in something, it has resonance modes and resonance frequencies. If there is an external periodic driving force (emotions in our case), the frequency of the force is going to find one of the resonance modes and once the mode is found, the amplitude grows exponentially. Time to find this mode depends on the strength (amplitude) of the driving force. The way to prevent or even stop the resonance is to keep changing the driving frequency: then the liquid forms steady patterns.
Well here I was thinking to myself "yeah yeah resonance hippie bullshit" but this does make a lot of sense.
