The legitimate concerns and justified anger tend to be characterized by long-term (multiple years), consistent pressure. People exerting it can listen to opposing views (without angry screams) and justify their own.
What we see today are angry flashes that can change direction on a whim. Flash mobs of statue tear-downs, coronavirus mask/no-mask outrages, etc. are in my view more of a symptom of pent-up aggression fanned by pre-election opportunism, not of legitimate concerns. My 2c.
With the exception of the coronavirus protests, everything else has had years of consistent pressure behind it.
There have been riots and protests over police brutality and systemic racism for years. People have been protesting America's whitewashing of its history and romanticizing of the Confederacy for years. None of these issues are new. The CHAZ wasn't the result of "pre-election opportunism," read their list of demands. It's fueled by anger, yes, but also seeks redress for grievances the black community has been complaining about for years. "Biden 2020" isn't in there anywhere.
