Else, few, and only fringe usually crazy people would not agree that e.g. slavery, seggregation, jim crow, redlining, etc, were and are bad.
But a certain modern "anti-racism" is not used against the establishment or the white privileged class, and is not even driven by blacks themselves demanding justice.
It's driven by upper middle class whites and their wanabees in-preparation (e.g. higher end college students), against lower class whites.
And as such, it's not just classist, but also blind to the injustices working class whites and "white trash", blacks, latinos, etc, face because of poverty and inequality - it serves as a class signal to perpetuate 'woke white supremacy' (and as a career to some).
Then again, what I know? I'm not American, and we have been actual slaves ourselves in my country...
