Yes, ~25 Americans were killed last year in connection to these things, but as this article shows, that may be as much about the presence of guns at these things than anything else— here's a pretty solid summary: https://www.theguardian.com/world/2020/oct/31/americans-kill...
Understanding why people do things, even bad things, is crucial to easing divisiveness.
I understand why people stormed the capitol. I do not condone their actions and hope they are all made examples of.
Just as I understand the hundreds of years of history that is behind this summers protests. I am far more sympathetic to the tens of millions that protested against fascism and racism then I am to the actual fascists that tried to usurp democracy and install a dictator while taking scalps.
When impoverished, abused, and neglected people peacefully take to streets en masse to demand change are met with brutal policing, that could be war crimes, instead of compromise and change what else do you honestly expect to happen? When millions of people can't afford to put on the table what do you expect them to do when the majority party fails to provide even a poverty level existence during a pandemic that disproportionately effects their demographic? Should they shut up and starve to death? Should they continue to take these beatings from police? Until the field is leveled don't expect this movement to die; they're fighting for their right to live.
Revenge and destruction and murder are justified so long as it doesn't interfer with a political process?
