We lived there for more than 10 years; my daughter lives there with our black grandchild. Here is the law... look it up.
The Florida Statute 1003.42 (h) explicitly requires teachers to cover various aspects of African American history, including the history of African peoples before slavery, the passage to America, the enslavement experience, abolition, and the contributions of African American society3.
the recent standard for teaching African American history prohibits the course being taught in a way that promotes the ideology that people today are victims or guilty of acts in the past based on their skin color.
Your link really misrepresents the course being taught today. No one is defending or justifying slavery instead the course designed by black scholars attempts to look at every aspect of black history without any preconceived narrative.
