Critical Race Theory teaches white children (oppressors) that they bear responsibility for the past discrimination and racism against non-whites (oppressed).
How can this be positive?
It is not intended to be positive. It is intended to promote tension leading to further racism and eventual breakdown of our society under the guise of racial justice. Children like my granddaughters grew up without the racial animus that characterised my generation. CRT wants to introduce it to them and make them accountable for this evil.
Clever Neo-Marxist trick.
