One of the main reasons for bad things to happen is the lack of education (which, in turn, leads to resist to change) and, therefore makes people prone to believe to unbelievable things.
Social platforms like Twitter should have long had things like "fact checking" ANY statements and should have restricting not only violence glorifying posts, but also the ones with racial or sexual discrimination and all the others .
It is late, but I like seeing it happen at least for the person with the most "glorifying" record in dividing a society.
But the ride the will be extremely profitable and business have shown to care more about short term than long term. Some examples are Nestle guzzling ground water during droughts, Johnson's baby powder with talc, the entire oil gas and coal industry, Pacific gas and electric company, etc.
