"The information is readily available, would such a disclosure, especially in the formative years, been Critical Race Theory, the truth, or both?"
I see CRT as more a study of "justice" than "truth" - the 'official story' isn't necessarily a lie (though it may be), so much as crafted selectively - prone to omit people. One interviews different witnesses not because some may lie, but because the whole story should be known.
Yes, "the information is readily available" - some pieces are focal points, others withheld. Historically, one learns of Al Capone/Prohibition and certain other stories - but Greenwood/Tulsa and the Red Summer got less attention. "Give me your tired, your poor, your huddled masses" is taught one way - the inherent irony of omitted peoples you've eloquently identified gets obscured.
I'll look forward to reading more of your thoughts and observations.
