The attack on "critical race theory" has little to do with theory and more a fear of:
1) historical accuracy
2) students recognizing a continuous line between atrocities of the US past and present
3) students recognizing parallels between atrocities in the US and other nations
When students learn the full scope of history, good and the bad, and that, as Arendt said, most evil is done by people who never make up their minds to be good or evil -- they may have greater expectations for the present. They may sense their place in history and make a choice.
In the epilogue of HIDING IN PLAIN SIGHT, I describe taking my children to historical sites around the US out of concern our history would be drastically rewritten in coming years -- but also because kids deserve truth. Knowledge is power. This is what opponents of accuracy fear.
