What are the objections to this sort of teaching?
Parent said in his comment, the teachings made his brown skinned child feel inferior, and he didn't feel this way as a child with the old way of teaching.
I also went to school in Virginia. The old way of teaching (at least in our school) was to pretend these factors didn't exist at all. This was incongruous with the way people were treated outside school, and led some to wonder what the school was hiding. Kids are perceptive, and they notice if there's a giant hole in what you're allowed to talk about.
