From the link in the OP, here is the exact wording of the Florida guidelines on this topic:
It is one of dozens of standards that Florida students are to be taught about slavery in the U.S. Others include the evolution of the triangular slave trade and discussion of the indentured servitude system that existed before slavery, the role of black patriots in the American Revolution, the underground railroad, how slavery affected the economy, the abolishionist movement, the Civil War, and other relevant history. Florida Republicans are not "banning the teaching of history," that is absurd drama from the left.
Do I agree with the above standard? Not fully. I don't have a problem with students learning the truth that some slaves were taught to be skilled laborers. But listing several such skills along with "agricultural work" might mislead the students, that most slaves did skilled labor.
In fact, the vast majority of slaves were engaged in "agricultural work," meaning they were doing the back breaking work of planting and harvesting cotton and tobacco, two crops that were labor intensive and whose methods were very unpleasant for the workers. It was difficult to get whites to do that kind of work, since they came from England and Europe to own farms, not to spend their lives working on someone else's.
Movies that have Roman slaves often show them as skilled workers, and even managers, and sometimes gladiators. But the overwhelming majority of those slaves worked on farms, doing the work that civilized Romans did not want to to. That's what slavery is: force people to do work that free people would not want to do.
So, I would change those standards if I were in charge of Florida education. I'm not. I'm a Texan, and I'm perfectly happy to let Florida be Florida. If the voters of Florida don't like it, they can change it. If liberals in Florida don't like it, and the vote doesn't go their way, they can head to Oregon where their kids can be taught that the root cause of slavery is the inherant evilness of Whites.
