- I think it is important to tell the truth about our history and the role of law in it, says Cliff Johnson, professor who himself holds a course in critical raste theory at the University of Mississippi School of Law.

"We need to focus on the things that make our children productive, as opposed to the things that teach them to be victims," ​​said Chris McDaniel (R), a state senator in Mississippi.

At least 17 states have now banned the teaching of Critical race theory, CRT.

The decisions are popular with Republican voters ahead of this fall's midterm elections.

The bans have the greatest impact on primary and secondary schools.

But really, the theory is taught almost exclusively in higher specialized educations.

Cliff Johnson leads a course in such higher education.
