You have done nothing, absolutely zero, to prove that Florida is different from Democratic party states in this regard. (1) It is still possible that Florida does teach this at an appropriate age level, but just doesn't explicitly mention it at the likely more generalized educational goals that you're looking at. (2) It is possible that no other states teach this, if indeed Florida doesn't teach it either. (3) This is a very explicit topic. Does any state's history curriculum teach about how in ancient Greek culture men often had younger boys as lovers, and such was certainly true of Alexander the Great, and that Socrates/Plato/Aristotle were all doing it, and that Thebes's whole warrior class explicitly had the homosexual partner construct? That's just as explicit. Raping African American slaves was terrible, but it's also one of those terrible things of a sort that's often left out of history books precisely because it's so explicit. Which brings me back to my initial point: You haven't proven that Democratic Party states, or any other states, teach this either.
