The groundswell of reaction in this country is coming from middle class and more affluent white people, especially the older ones, who are angry over a perceived but insignificant loss of status in a world that still revolves almost entirely around them.
It's easy for them to rile up poor and racist white people, obviously, seeing as they control the media they consume, which spews out an endless stream of scaremongering about crime, immigration, critical race theory, trans people, etc.
