Race riots are not expressions of hopelessness, they’re impressions of perceived power. Before 1963, race riots that involved black and white issues were almost entirely white-led, after that year, almost entirely black-led. This means that something must have happened in 1963 give or take a year that sent a sociopolitical message that the racial worm was turning away from whites and in favor of blacks.
Which means the group that does the rioting is the group that does or thinks it has the power.
As weird as it feels to say this, this means I’m glad white people somewhere are engaging in a race riot. The only kinds of white Americans that will riot anymore are sports dorks.
