Racism knows no bounds.  For years I've tried to point out bias of many kinds, including the bias of racial typecasting, including on this site.        

Part of me feels a bit smug toward those who said claims of racism were just liberal fantasy, or that they held no racial bias themselves.   Recent events have shown deep racism that leads to violence in not unusual nationally from the public dialog it's clear that the much less virulent form of bias and prejudice is widespread.  

The nation has been helped by the public exposure of an illness that can still be managed.  That's a good thing.    Left untreated the disease will kill.
